cairo: Update to 1.16.0.
Release 1.16.0 (2018-10-19 Bryce Harrington <bryce@bryceharrington.org>) ======================================================================== This new stable release incorporates a number of improvements made in the four years since 1.14.0. Of particular note is a wealth of work by Adrian Johnson to enhance PDF functionality, including restoring support for MacOSX 10.4, metadata, hyperlinks, and more. Much attention also went into fonts, including new colored emoji glyph support, variable fonts, and fixes for various font idiosyncrasies. Other noteworthy changes include GLESv3 support for the cairo_gl backend, tracking of SVG units in generated SVG documents, and cleanups for numerous test failures and related issues in the PDF and Postscript backends. For a complete log of changes, please see https://cairographics.org/releases/ChangeLog.1.16.0 Features and Enhancements ------------------------- * Add support for OpenGL ES 3.0 to the gl backend. * The PDF backend has gained support for a range of widely used features, including thumbnails, page labels, metadata, document outlines, structured text, hyperlinks, and tags. Tags permit adding logical info such as headings, tables, figures, etc. that facilitates indexing, accessibility, text reflow, searching, and extraction of the tagged items to other software. For details on this new PDF functionality, see: https://lists.cairographics.org/archives/cairo/2016-June/027427.html * Variable font support. Variable fonts are single font files with various typography characteristics, such as weight or slant, that users of the font can adjust between two points. Effectively this enables a single font to behave as multiple fonts. * Restore MacOSX 10.4 support. Cairo had dropped 10.4 support when moving to the CoreText API. Now we automatically detect which API to use via dynamic linking, so can resume supporting this older version of MacOSX. * Support colored emoji glyphs, stored as PNG images in OpenType fonts. * Skia backend is removed * Use Reusable streams for forms in Level 3 Postscript. * Add CAIRO_MIME_TYPE_EPS mime type for embedding EPS files. * Add CCITT_FAX mime type for PDF and PS surfaces * svg: add a new function to specify the SVG document unit (Bug #90166) * Use UTF-8 filenames on Windows API Changes ----------- Several new APIs were added. No existing APIs were altered. New PDF functionality: * cairo_pdf_surface_add_outline * cairo_pdf_surface_set_metadata * cairo_pdf_surface_set_page_label * cairo_pdf_surface_set_thumbnail_size * cairo_tag_begin * cairo_tag_end * CAIRO_STATUS_TAG_ERROR New error status items for problems relating to PDF tagging: * CAIRO_STATUS_WIN32_GDI_ERROR * CAIRO_STATUS_FREETYPE_ERROR * CAIRO_STATUS_PNG_ERROR New error status items for handling of GDI, libfreetype, and libpng errors, respectively. Setting up Win32 surfaces for HDC with alpha channels: * cairo_win32_surface_create_with_format New API for added PDF functionality (see above), and new error status item for problems relating to PDF tagging. Variable fonts: * cairo_font_options_get_variations * cairo_font_options_set_variations Tracking units in SVG documents: * cairo_svg_surface_set_document_unit * cairo_svg_surface_get_document_unit Dependency Changes ------------------ None Performance Optimizations ------------------------- None Notable Bug Fixes ----------------- * Fix thin lines that don't show up when printing in Inkscape due to overly aggressive culling. (Bug #77298) * Fix playback of recording surfaces into PDF surfaces, where objects with negative coordinates were not getting drawn. To address this, the coordinate systems for PDF and PS have been changed to match cairo's coordinate system. This allows recording surfaces to be emitted in cairo coordinates, and results in the same origin being used for all operations when using the recording surface XObject. Test cases for PDF and PS have also been updated accordingly. (Bug #89232) * Fix "invalidfont" error on some printers when printing PDFs with embedded fonts that have glyphs (such as spaces) with num_contours == 0. (Bug #79897) * Fix missing glyphs such as thin dashes, which get scaled to 0 in userspace and thus have their drawing operations culled. (Bug #94615) * Fix other oddities caused by variously idiosyncratic fonts. * Fix a data race in freed_pool discovered by Firefox's cairo usage. The patch adads atomic int load and store functions, with relaxed memory ordering. (Bug #90318) * Handle SOURCE and CLEAR operators when painting color glyphs. (Bug #102661) * Fix falling back to system font with PDFs using certain embedded fonts, due to truncated font names. (Bug #103249) * Prevent curved strokes in small ctms from being culled from vector surfaces (Bug #103071) * Fix assertion hit with PDFs using Type 4 fonts rendered with user fonts, due to error when destroying glyph page. (Bug #103335) * Prevent invalid ptr access for > 4GB images. (Bug #98165) * pdf: Fix internal links pointing to other pages, by pre-calculating page heights so that link positions can be calculated more accurately. * Fix error reporting in the xcb backend if fallback fails. Instead of returning NULL when the X11 server can't do some operation, return a surface in an error state. * Clarify documentation regarding device scale inheritance and the units used in cairo_surface_create_similar_image. (Bug #99094) * Call XSync in the xlib backend before setting the error handler to ignore errors for certain requests, to make sure all pending errors are handled first. * Fix regression with text containing space character on Win32. (Bug: https://gitlab.freedesktop.org/cairo/cairo/issues/339) For a more comprehensive listing of fixed bugs, see the release notes for the individual 1.15.x releases. Release 1.15.14 (2018-09-19 Bryce Harrington <bryce@bryceharrington.org>) ============================================================================ We're nearly ready to finalize the 1.16.0 release, so this snapshot can be considered a beta for 1.16. The most notable change this release is a performance optimization for windows, discussed below. Other than that, much of the development focus was on final polish and stability as we prepare for 1.16. Some attention went into getting the testsuite passing at least for the image backend. The Cairo testsuite depends on external software like Pixman, and changes in the rendering behavior of these dependencies change test behavior, leading to false positives. Results from the Coverity static testing tool were also reviewed. Most of the issues flagged were false positives, but there were several legitimate problems found and fixed. For a complete log of changes, please see https://cairographics.org/releases/ChangeLog.1.15.12 Features and Enhancements ------------------------- * Add more FreeeType font color conversions to support COLR/CPAL * Update test reference images against current pixman API Changes ----------- None Dependency Changes ------------------ None Performance Optimizations ------------------------- Vasily Galkin introduced a Win32 performance optimization for CAIRO_OPERATOR_SOURCE when copying data from a backbuffer to an argb32 surface corresponding to a Win32 DC. With this, argb32 drawing should perform as fast as typical dibsection-buffered GDI drawing. See the Cairo mailing list for April 2018 for data and discussion of the performance improvements. Bug Fixes --------- * Fix crash when rendering Microsoft's Segoe UI Emoji Regular font. * Fix build breakage with glesv3 enabled due to non-existant glesv3.pc. * Fix memory leaks found by Coverity * Fix incorrect null ptr handling found by Coverity * Fix test compilation when font-config is disabled * Use _cairo_malloc instead of malloc (Bug #101547) (CVE-2017-9814) * Fix assertion failure in the freetype backend (Bug #105746) Release 1.15.12 (2018-04-04 Bryce Harrington <bryce@osg.samsung.com>) ======================================================================== The main focus for this release is the addition of Variable Font support. Variable fonts are single font files with various typography characteristics, such as weight or slant, that users of the font can adjust between two points. Effectively this enables a single font to behave as multiple fonts. The Skia backend is disabled in this release, due to severe bitrot, and will be removed in future releases. Contact the cairo team if you have a need of this backend. For a complete log of changes, please see https://cairographics.org/releases/ChangeLog.1.15.12 Features and Enhancements ------------------------- * Variable font support * Skia backend is disabled API Changes ----------- * cairo_font_options_get_variations() and cairo_font_options_set_variations() are added. Dependency Changes ------------------ None Performance Optimizations ------------------------- None Bug Fixes --------- * Fix errors in csi-trace --help and --version options * Fix a 'memory leak' in the image compositor, with pixman_glyph_cache_t. * Fix access of uninitialized memory found by valgrind (Bug #91271) * Fix improper initialization of memory in _cairo_ft_font_face_create_for_pattern() (Bug #105084) * Fix multi-monitor virtual desktop with negative coords on Win32 (Bug #100793) * Fix issues occuring with older FreeType versions. Release 1.15.10 (2017-12-07 Bryce Harrington <bryce@osg.samsung.com>) ======================================================================== This release adds GLESv3 support to the cairo_gl backend, adds tracking of SVG units in generated svg documents, and cleans up numerous test failures and related issues in the PDF and Postscript backends.

Update to 1.14.2:
Release 1.14.2 (2014-03-09 Bryce Harrington <bryce@osg.samsung.com>) ==================================================================== This release provides collected bug fixes, along with one feature enhancement for the xcb backend, and a small performance improvement for fonts. The running theme of the bug fixes is platform-specific issues, both build and run-time. Platforms with fixes include Sparc, AIX, Windows (mingw), and Windows (MSVC8). Memory leaks, valgrind issues, and PDF issues round out our list. It's come to light that changes in cairo 1.14 resulted in breakage on MacOS X 10.4. We've not yet determined whether to fix up the support, or excise the 10.4-specific code and support only OS X 10.5 or newer. Meantime, we'll only advertise cairo as working on OS X 10.5. Features -------- * Improve xcb's handling of per-screen subpixel ordering. If no Xft.rgba property is specified, default to the screen's subpixel order. API Changes ----------- None Dependency Changes ------------------ None Performance Optimizations ------------------------- * Improve performance of cpu_to_be32 and be32_to_cpu, making truetype subsetting of large fonts run about 15% faster. Bug Fixes --------- * Fix unaligned access on sparc with the compact font format (CFF). Unlike truetype, all data in CFF is not aligned. (Debian bug #712836) * Fix unaligned access on sparc with tor-scan-converter's memory pool. * Fix crash when loading a PDF with a transformed image. (fdo bug #85151) * Fix regression on mingw for bigendian test due to removal of file extension for executables. (fdo bug #85120) * Fix handling of backslash in PDF interpreter (fdo bug #85662) * Fix crash in xlib and xcb renderers when swapping a 0-sized glyph * Fix bug with RTL text in PDF operators (fdo bug #86461) * Fix compilation 'cairo-path-stroke-traps.c' with MSVC8 (fdo bug #84908) * Fix crash in _fill_xrgb32_lerp_opaque_spans when a span length is negative. * Fix valgrind error by releasing pattern created by cairo_pattern_create_rgb(). * Fix valgrind errors when running cairo-test-suite. * Fix memory leak in recording surface replays (fdo bug #87898) * Fix destruction of fonts in api-special-cases test. (fdo bug #87567) * Fix duplicated surface push on similar-image, preventing trivial GTK3 program traces from being replayable, with an error message about invalid values for the size of the input. (fdo bug #73580) * Fix crash when win32 surface's image size does not cover the entire surface. (fdo bug #53121) * Fix crash due to obsolete CGFontGetGlyphPath call (fdo bug #84324) * Fix several build issues on AIX (fdo bugs #89338, #89340, #89356, #89354) * Fix various documentation warnings and errors |

Update cairo to 1.14.0:
Release 1.14.0 (2014-10-13 Bryce Harrington <bryce@osg.samsung.com>) ==================================================================== Hard to believe it's been over a year since our last release, but it's not for lack of activity. This release includes contributions of a wide assortment of bug fixes, build system improvements, warnings cleanups, codebase refactoring, test suite repairs, and static analysis work. This release is lighter on features (compared with 1.12.10) but includes a highly demanded rehaul of our image downscaling functionality, which solves a serious problem experienced by Inkscape users when shrinking embedded bitmaps in SVG files. The new scaling algorithms are used by the image backend and by other backends as needed for fallbacks. Features -------- Filtering improvements for the image backend, in particular down-scaling of images produces filtered images that depend on all the pixels of the source. When using the image backend you get the following settings: CAIRO_FILTER_GOOD: uses a box filter for scales less than .75 in either direction. For scales larger than this, the same filter as CAIRO_FILTER_BILINEAR is used. CAIRO_FILTER_BEST: uses a Catmull-Rom filter always. When upscaling more than 2x this will produce anti-aliased square pixels, similar to OS/X. CAIRO_FILTER_GAUSSIAN: uses PIXMAN_FILTER_BEST, which in current pixman is the same as BILINEAR. (This is subject to change in the future). xlib and xcb also use the image fallback for GOOD/BEST filters, but note that other backends do not implement these filtering fixes yet, however other actions may cause them to use an image fallback which will cause these filters to be used. Improve handling of device transformation and scaling, allowing Cairo to now support scaling at a device level, permitting easier, more transparent HiDPI support. Support JBIG2 mime data in PDF. This allows embedding of more compressed JPEG formats within PDF, rather than including the full uncompressed image. Also, reduce the number of transparency groups used by PDF to keep the file size small and viewing/printing of the PDF fast. Expand the embedding section to include stencil mask support. Reorder font declarations to be in natural order. Update the Skia backend to build against current Skia (as of June 2014). Drop Link-Time Optimization (LTO) support from build system. This seems to have caused much trouble for unclear benefit, and most distros are reverting or disabling it anyway. Optimize VBO size on GL to 1M and to 16k for EGL. This improves (theoretical) performance for desktop GLX use cases while avoiding hitting VBO memory size limitations on embedded devices. API Changes ----------- cairo_surface_set_device_scale, cairo_surface_get_device_scale: Sets a scale that is multiplied to the device coordinates determined by the CTM when drawing to @surface. One common use for this is to render to very high resolution display devices at a scale factor, so that code that assumes 1 pixel will be a certain size will still work. cairo_egl_device_get_display, cairo_egl_device_get_context: Support get/set of EGLContext and EGLDisplay for egl-based cairo devices, similar to GLX. Dependency Changes ------------------ Cairo now requires glib 2.14 for its gobject helper functions, and pixman 0.30 for downscaling. Bug fixes --------- Don't embed CMYK Jpeg images in svg. Fix tests to place output in proper location. Fix determination of alpha for all surfaces when recording. Extend oversize check to cairo_gl_surface_create_for_texture, so an error surface is returned if the texture is too large to render to. Fix embedding of mime data in PDF and PS files. Remove useless error handling in *_reply() functions in XCB. Fix a double-free exposed by multithreaded apps creating and destroying the same font concurrently. https://bugs.freedesktop.org/show_bug.cgi?id=69470 Fix corrupt stacks produced by bugs in operand emission for trace. Fix out of bounds array access in format cache for xlib Don't rename glyphs used by seac operator. This can cause certain combined characters to use their decorations (e.g. umlauts on ö) to be lost during printing of PDFs using evince. https://bugs.freedesktop.org/show_bug.cgi?id=70364 Fix crash on calling cairo_create with a finished surface Fix SSIZE_T definition problem when making with MSYS on Windows7 Fix one off issue in gl context cleanup Fix usage of CAIRO_STACK_ARRAY_LENGTH Fix rectangle stroke with non rectilinear pen Fix imagemask with pattern source failure on some printers. This bug could cause files converted using pdftops to fail for example on Ricoh printers, or opening in Adobe Distiller on Windows. https://bugs.freedesktop.org/show_bug.cgi?id=69485 Fix whitespace in font names Fix page size in generated PDFs. When printing using pdftocairo on larger page sizes, such as 11x17, the image would be cropped to letter size. https://bugs.freedesktop.org/show_bug.cgi?id=73452 Fix path-currentpoint test by preserving current-point in copy_path()/append_path() sequence Fix generation of HTML in code docs for cairo-format-stride-for-width. Raw HTML code was being passed to the browser, instead of displaying normally. https://bugs.freedesktop.org/show_bug.cgi?id=63257 Fix spelling of "tessellator" throughout code. We're using the American rather than British spelling of this word. https://bugs.freedesktop.org/show_bug.cgi?id=50411 Fix crash in pixman_image_composite32 Fix crash when trying to modify a (const) all-clipped cairo_clip_t https://bugs.freedesktop.org/show_bug.cgi?id=75819 Add check_composite method to all compositors, to fix crashes in the test suite. Fix crash in Firefox when scrolling on certain pages. Fix memory leaks found by static analysis. Fix build of any2ppm if fork is not available. Fix broken build for Qt backend, due to missing libstdc++. Fix typo in two cairo_uint128 functions. Fixes potential build issues on systems without a uint128 type. Fix build when --enable-pdf=no Fix cache_frozen assertions for Win32 print. Correctly check for xcb image surface for inplace upload Fix webkit-based web browser crashes due to empty boxes by skipping over them when tesselating. Make pixman, libpng, and zlib paths commandline configurable for win32 builds. Fix image scale on Win32 when GDI scale is not identity. Fix float endian configure test when using clang -O4 Fix compilation with Android bionic libc Don't try to build util/sphinx on Windows Fix loss of precision when emitting joins. This was caused by discrepancies in line gradients when passing trapezoids around. Fix loss of precision and associated rendering issues in cairo-tor-scan-converter from projection onto sample grid. Fix pixman oversampling of neighbouring edges within a cell by eliminating self-intersections for the pixman traps compositor. Fix multi-line string splitting in PDFs Various cleanups and fixes to warnings, documentation, tests, and build system. Improve error handling and return value checks. Cleanup XFAIL tests and reference images. Cover recently added functionality. |

Update cairo* to 1.12.14:
Release 1.12.14 (2013-02-10 Chris Wilson <chris@chris-wilson.co.uk>) ==================================================================== In the last week we had a few more bugs reported and promptly resolved. As these are a combination of regressions and stability issues, it is time for a prompt update and release. Many thanks to everyone for testing and reporting issues, and helping to make Cairo better. Bug fixes --------- Prevent user callbacks accessing user-data during destroy to prevent use-after-free bugs. https://bugzilla.mozilla.org/show_bug.cgi?id=722975 Use standard names for glyphs in subset fonts (PDF). https://bugs.freedesktop.org/show_bug.cgi?id=60248 Fix detection of Win98. The logic for detecting Win98 (and its broken AlphaBlend()) was inverted, disabling AlphaBlend() for everyone. Prevent numeric overflow from extrapolating polygon edges to the clip boundary and causing severe render artifacts. https://bugs.freedesktop.org/show_bug.cgi?id=60489 Fix computation of glyph string coordinates when breaking up runs for xlib.

Update to 1.12.12:
Release 1.12.12 (2013-01-31 Chris Wilson <chris@chris-wilson.co.uk>) =================================================================== The goal of this release is to fix the synchronisation problems that were exhibited in the SHM transport for cairo-xlib. This cropped up any place that tried to rapidly push fresh pixel data to the X server through an ordinary image surface, such as gimp-2.9 and evince. Bug fixes --------- Avoid replacing the entire image when uploading subimages https://bugs.freedesktop.org/show_bug.cgi?id=59635 Force synchronisation for scratch SHM image buffers, so that we do not overwrite data as it is being read by X. https://bugs.freedesktop.org/show_bug.cgi?id=59635 (also) Fix typos in detecting multisampling for the GL (MSAA) backend. Fix a memory leak in the GL (MSAA) backend. Fix a reference counting bug when mapping a GL surface to an image. |

Update to 1.12.10:
Release 1.12.10 (2013-01-16 Chris Wilson <chris@chris-wilson.co.uk>) =================================================================== A heap of bug fixes everywhere, and the gradual completion of the MSAA backend for cairo-gl. Perhaps the most noteworthy set of the bugfixes was the crusage lead by Behdad Eshfabod to make font handling by pango/cairo/fontconfig fully threadsafe. This testing revealed a couple of races that needed fixing in Cairo's scaled-font and glyph cache. Bug fixes --------- Append coincident elements to the recording's surface bbtree so that the list is not corrupted and the overlapping elements lost. Fix cairo-trace to correctly record map-to-image/unmap-image and then replay them. Ignore MappingNotifies when running the XCB testsuite as they are sent to all clients when the keyboard changes. The testsuite would detect the unexpected event and complain. Handle very large large images in the XCB backend. Fix a memory leak in the xlib/shm layer, and prevent use of the SHM surfaces after the display is closed. https://bugs.freedesktop.org/show_bug.cgi Handle resizing of bitmap fonts, in preparation for a fix to fontconfig to correctly pass on the user request for scaling. Always include subroutine 4 (hint replacement idion) when subsetting type 1 fonts in order to prevent a crash in cgpdftops on Mac OS/X Fix a couple of typos in the cairo-gobject.h header files for introspection. Prevent a mutex deadlock when freeing a scaled-glyph containing a recording-surface that itself references another scaled-glyph. https://bugs.freedesktop.org/show_bug.cgi?id=54950 Make scaled-font cache actually thread-safe and prevent use-after-frees. Restore support for older versions of XRender. A couple of typos and a few forgotten chunks prevented the xlib compositor from running correctly with XRender < 0.10. Note that there are still a few regressions remaining. |

Many thanks to everyone who reported their issues and helped us track down the bugs and helped testing the fixes. Bug fixes --------- Expand the sanity checking for broken combinations of XSendEvent and ShmCompletionEvent. Notice that "The X.Org Foundation" sometimes also identifies itself as "The Xorg Foundation". Handle various ages of libXext and its Shm headers. Fix the invalid clipping of the source drawable when using SHM transport to upload images. https://bugs.freedesktop.org/show_bug.cgi?id=56547 Handle all Type1 postscript operators for better font compatibility. https://bugs.freedesktop.org/show_bug.cgi?id=56265 Fix a couple of memory leaks in Type1 font subsetting https://bugs.freedesktop.org/show_bug.cgi?id=56566 Tighten the evaluation of the start/stop pen vertices, and catch a few instances where we would use a fan instead of a bevel. https://bugs.freedesktop.org/show_bug.cgi?id=56432 Fix assumption that geometric clipping always succeeds with the span-compositor. https://bugs.freedesktop.org/show_bug.cgi?id=56574 Fix call to spline intersection when evaluating whether a stoke is visible.

Release 1.12.6 (2012-10-22 Chris Wilson <chris@chris-wilson.co.uk>) =================================================================== Thanks to everyone who download cairo-1.12.4 and gave us their feedback. It truly was invaluable and has helped us to fix many portability issues that crept in with some of the new features. This release aims to fix those stability issues and run on a wider range of systems. Bug fixes --------- Fix the recording surface to actually snapshot the source and so fix PDF drawing. Calling XSendEvent with an XShmCompletionEvent is incompatabile with older Xorg servers. Reorder CloseDisplay chain so that XShm is not reinstantiated after shutdown, causing a potential crash if the Display was immediately recreated using the same memory address. Make sure that the Xserver has attached to the SHM segment before deleting it from the global namespace on systems that do not support deferred deletion. Type1 subsetting support for PDF (and PS) was once again improved to work with a larger number of PDF readers. GLESv2 build fixes and improved support for embedded GPUs. Tweak the invisible pen detection for applications that are currently using too large values for geometric tolerance. A build fix for older freetype libraries. |

Downgrade cairo back to yesterday's version.
1.12.4 causes SHM problems on OS X and NetBSD. E.g. for firefox, during startup, on 6.99.12/amd64: ###!!! ABORT: X_ShmAttach: BadAccess (attempt to access private resource denied); 11 requests ago: file /scratch/devel/xulrunner/work/mozilla-release/toolkit/xre/nsX11ErrorHandler.cpp, line 157 ###!!! ABORT: X_ShmAttach: BadAccess (attempt to access private resource denied); 11 requests ago: file /scratch/devel/xulrunner/work/mozilla-release/toolkit/xre/nsX11ErrorHandler.cpp, line 157 zsh: segmentation fault (core dumped) firefox Or for xchat on OS X Lion: The program 'xchat' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAccess (attempt to access private resource denied)'. (Details: serial 5738 error_code 10 request_code 133 minor_code 1) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) |

Update to 1.12.4:
Release 1.12.4 (2012-10-05 Chris Wilson <chris@chris-wilson.co.uk>) =================================================================== More bugs, and more importantly, more fixes. On the cairo-gl side, we have refinements to the MSAA compositor which enables hardware acceleration of comparitively low-quality antialiasing - which is useful in animations and on very high density screens. For cairo-xlib, we have finally enabled SHM transport for image transfers to and from the X server. A long standing required feature, SHM transport offers a notable reduction in rendering latency by reducing the number of copies required to upload image data - given hardware and driver support, cairo-xlib can now perform zero copy uploads onto the GPU. And as usual Adrian Johnson has been very busy fixing many different corner cases in cairo-pdf, impoving opacity groups and font subsetting. Last, but not least, for cairo-image Søren Sandmann Pedersen added support for rendering glyphs to pixman and using that from within cairo. The new glyph rendering facility reduces the overhead for setting up the compositing operation, improving glyph thoughput for the image backend by a factor of about 4. And before he did so, he also fixed up a few bugs in the existing glyph rendering code. So many thanks to Andrea Canciani, Adrian Johnson, Chuanbo Weng, Dongyeon Kim, Henry Song, Martin Robinson, Søren Sandmann Pedersen and Uli Schlachter for their contributions, finding and fixing bugs.

Update to 1.10.0. Add default-on xcb option (implying x11 option).
Release 1.10.0 (2010-09-06 Chris Wilson <chris@chris-wilson.co.uk>) =================================================================== The cairo community is astounded (and flabbergast) to finally announce the 1.10.0 release of the cairo graphics library. This is a major update to cairo, with new features and enhanced functionality which maintains compatibility for applications written using any previous major cairo release, (1.8, 1.6, 1.4, 1.2, or 1.0). We recommend that anybody using a previous version of cairo upgrade to cairo 1.10.0. One of the more interesting departures for cairo for this release is the inclusion of a tracing utility, cairo-trace. cairo-trace generates a human-readable, replayable, compact representation of the sequences of drawing commands made by an application. This can be used to inspecting applications to understand issues and as a means for profiling real-world usage of cairo. The traces generated by cairo-trace have been collected in git://git.cairographics.org/git/cairo-traces and have driven the performance tuning of cairo over the last couple of years. In particular, the image backend is much faster with a new polygon rasterisation and a complete overhaul of the tessellator. Not only is this faster, but also eliminates visual artifacts from self-intersecting strokes. Not only has cairo-trace been driving performance improvements within cairo, but as a repeatable means of driving complex graphics it has been used to tune OpenGL, DDX, and pixman. Cairo's API has been extended to better support printing, notably through the ability to include a single compressed representation of an image for patterns used throughout a document, leading to dramatic file size reductions. Also the meta-surface used to record the vector commands compromising a drawing sequence is now exposed as a CAIRO_SURFACE_TYPE_RECORDING, along with a new surface that is a child of a larger surface, CAIRO_SURFACE_TYPE_SUBSURFACE. One typical usage of a subsurface would be as a source glyph in a texture atlas, or as a restricted subwindow within a canvas. Cairo's API has also resurrected the RGB16 format from the past as the prevalence of 16-bit framebuffers has not diminished and is a fore-taste of the extended format support we anticipate in the future. Increasing cairo's utility, we introduce the cairo_region_t for handling sets of pixel aligned rectangles commonly used in graphics applications. This is a merger of the GdkRegion and the pixman_region_t, hopefully providing the utility of the former with the speed of the latter. Furthermore cairo has been reworked to interoperate more closely with various acceleration architectures, gaining the ability to share those hardware resources through the new cairo_device_t. For instance, with the new OpenGL backend that supersedes the Glitz backend, hardware and rendering operations can be shared between a classic OpenGL application mixing libVA for the hardware assisted video decode with cairo for high quality overlays all within the same OpenGL canvas. Many thanks for the hard work of Adrian Johnson, Andrea Canciani, Behdad Esfahbod, Benjamin Otte, Carl Worth, Carlos Garcia Campos, Chris Wilson, Eric Anholt, Jeff Muizelaar, Karl Tomlinson, M Joonas Pihlaja, Søren Sandmann Pedersen and many others that have contributed over the last couple of years to cairo. Thank you all! Snapshot 1.9.14 (2010-07-26) ============================ A quiet couple of weeks, hopefully Cairo is seeing widescale deployment and we are being to see the results of the stabilisation effort. Clipping bugs seems to have been the order of the last couple of weeks, with a couple reported and duly fixed. Thank you Igor Nikitin and Karl Tomlinsion for finding those regressions. At this point all that seems to remain to do is to fix the outstanding regressions in the PDF backend... Bugs fixes ---------- Clip doesn't work for text on the image backend https://bugs.freedesktop.org/show_bug.cgi?id=29008 Add explicit dependency for cxx https://bugs.freedesktop.org/show_bug.cgi?id=29114 Fix regressions in reporting clip extents https://bugs.freedesktop.org/show_bug.cgi?id=29120 https://bugs.freedesktop.org/show_bug.cgi?id=29121 https://bugs.freedesktop.org/show_bug.cgi?id=29122 https://bugs.freedesktop.org/show_bug.cgi?id=29124 https://bugs.freedesktop.org/show_bug.cgi?id=29125 Snapshot 1.9.12 (2010-07-12) ============================ A couple of weeks spent fixing those annoying bugs and cleaning up the build system; the list of outstanding tasks to complete for the stable release is finally shrinking. The chief bug fixer has been Benjamin Otte who not only made sure that the public API is consistent and being tested for its consistency, but also ensured that the documentation was up-to-date and spent time clarifying cases where even the Cairo developers have come unstuck in the past. Many thanks, Benjamin. However, he was not alone, as Andrea Canciani continued his fine work in isolating broken corner cases and proceeding to fix them, and tidying up the quartz backend. And last, but definitely not least, M Joonas Pihlaja tried building Cairo across a perverse range of systems and fixed up all the loose bits of code that came unravelled. Thanks everybody! API Changes ----------- cairo_surface_set_mime_data, cairo_surface_get_mime_data: The length parameter is now an unsigned long (as opposed to an unsigned int). The parameter is intended to be an equivalent to a size_t without requiring POSIX types and be large enough to store the size of the largest possible allocation. cairo_gl_surface_create_for_texture: This a new surface constructor for cairo-gl that explicitly enables render-to-texture for foreign, i.e. application, textures. cairo_region_xor, cairo_region_xor_rectangle A couple of utility routines add to the region handling interface for the purpose of replacing existing GdkRegion functionality. Bugs fixes ---------- https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/600622 Inkscape was caught in the act of attempting to modify a finished surface. Unfortunately, we had the ordering of our guards and assertions wrong and so an ordinary application error was triggering an assert in Cairo. This lead Benjamin to add a test case to ensure that the entire public API could handle erroneous input and then proceeded to fix a whole slew of uncovered bugs. https://bugs.freedesktop.org/show_bug.cgi?id=28888 A regression introduced by the special casing of uploading images to an xlib surface in-place which was ignoring the translation applied to the image. Snapshot 1.9.10 (2010-06-26) ============================ The first "quick" snapshot in the run up to the stable release. The last snapshot was picked up by the bleeding edge distributions and so the bug reports have to started to roll in. The most frequent of these are the introduction of rendering errors by applications that modify a surface without subsequently calling cairo_surface_mark_dirty(). Make sure the application developers are aware of increased reliance on strict use of the Cairo API before 1.10 is released! The usual slew of bugs reported and we would like to thank Zoxc for contributing the WGL interface for cairo-gl, and finding more build failures on win32. And it just wouldn't be a 1.9 snapshot unless Benjamin Otte improved the error handling within cairo-gl, as well as isolating and fixing some more errors in the test suite. The biggest bug of the snapshot turned out to be a major sign extension issue that had lain hidden for many years and was suddenly exposed by incorrectly rounding rectangles when performing non-antialiased rendering. Also to the relief of many we have included the downstream patch to honour the user's LCD filtering preferences for subpixel rendering of fonts. The interface remains private for the time being, whilst the proposed public API is finalized. API changes ----------- None. Snapshot 1.9.8 (2010-06-12) =========================== One major API changes since the last snapshot, and a whole slew of bugs fixed and inconsistencies eliminated. Far too many bugs fixed to individually identify. We need to thank Benjamin Otte for his fantastic work on the cairo-gl backend making it faster and more robust, Andrea Canciani for finding so many bugs and developing test cases for them, as well fixing them. And last but not least we must all thank Adrian Johnson for continuing to eliminate bugs and improving the PostScript and PDF backends. This snapshot represents almost 4 months of bug fixing, bringing Cairo to a point where we consider it almost ready to be a candidate for release. There are a few known bugs left to be fixed, being tracked in https://bugs.freedesktop.org/show_bug.cgi?id=24384, so please give Cairo a whirl and report any regressions. The plan is to release a new snapshot every other week leading to a 1.10 release with a target date of 2010-08-16. API additions ------------- CAIRO_FORMAT_RGB16_565 16 bit devices still remain popular, and so with great demand, CAIRO_FORMAT_RGB16_565 has been restored enabling applications to create and use 16 bit images as sources and render targets. cairo_surface_create_for_rectangle() It is common practice to cut an image up into many smaller pieces and use each of those as a source - a technique called texture atlasing. cairo_surface_create_for_rectangle() extends Cairo to directly support use of these subregions of another cairo_surface_t both as a source and as a render target. cairo_region_create() cairo_region_create_rectangle() cairo_region_create_rectangles() cairo_region_copy() cairo_region_reference() cairo_region_destroy() cairo_region_equal() cairo_region_status() cairo_region_get_extents() cairo_region_num_rectangles() cairo_region_get_rectangle() cairo_region_is_empty() cairo_region_contains_rectangle() cairo_region_contains_point() cairo_region_translate() cairo_region_subtract() cairo_region_subtract_rectangle() cairo_region_intersect() cairo_region_intersect_rectangle() cairo_region_union() cairo_region_union_rectangle() The Cairo region API was actually added a couple of snapshots ago, but we forgot to mention it at the time. A simple API for the handling of rectangular pixel-aligned regions by Soeren Sandmann. Backend-specific improvements ----------------------------- cairo-gl Benjamin Otte made more than 200 commits in which he refactored the cairo-gl backend, reducing a lot of code duplication and enabled him to begin working on improving performance by reducing state changes and associated overhead. cairo-xlib Access to the underlying connection to the Display is now thread-safe enabling cairo-xlib to be used in a multi-threaded application without fear of random corruption. Thanks Benjamin Otte! cairo-xlib will now attempt to use PolyModeImprecise when compositing trapezoids (i.e. a fill or a stroke operation with a non-trivial path) which should allow hardware drivers more scope for accelerating the operation at the cost of potentially incurring minute rendering errors. The mode can be forced back to PolyModePrecise by setting the antialias parameter to CAIRO_ANTIALIAS_SUBPIXEL. cairo-svg A notable improvement was contributed by Alexander Shulgin to enable SVG to reference external image through the use an extended MIME data type. Snapshot 1.9.6 (2010-02-19) =========================== API additions ------------- Add cairo_device_t The device is a generic method for accessing the underlying interface with the native graphics subsystem, typically the X connection or perhaps the GL context. By exposing a cairo_device_t on a surface and its various methods we enable finer control over interoperability with external interactions of the device by applications. The use case in mind is, for example, a multi-threaded gstreamer which needs to serialise its own direct access to the device along with Cairo's across many threads. Secondly, the cairo_device_t is a unifying API for the mismash of backend specific methods for controlling creation of surfaces with explicit devices and a convenient hook for debugging and introspection. The principal components of the API are the memory management of: cairo_device_reference(), cairo_device_finish() and cairo_device_destroy(); along with a pair of routines for serialising interaction: cairo_device_acquire() and cairo_device_release() and a method to flush any outstanding accesses: cairo_device_flush(). The device for a particular surface may be retrieved using: cairo_surface_get_device(). The device returned is owned by the surface. API changes (to API new in the cairo 1.9.x series) -------------------------------------------------- cairo_recording_surface_create() cairo_recording_surface_ink_extents() These are the replacement names for the functions previously named cairo_meta_surface_create and cairo_meta_surface_ink_extents. cairo_surface_set_mime_data This interface is now changed such that the MIME data will be detached if the surface is modified at all. This guarantees that the MIME data will not become out of synch due to surface modifications, and also means that for the MIME data to be useful, it must be set after all modifications to the surface are complete. API removal (of experiment API) ------------------------------- The cairo-glitz backend is removed entirely, (in favor of the new cairo-gl backend). See below for more on cairo-gl. Generic fixes ------------- Many improvements for drawing of dashed strokes Fix incorrect handling of negative offset Faster computation of first dash (avoids near-infinite looping) Approximate extremely fine dash patterns with appropriate alpha value Optimize spans-based renderers for repeated rows, (such as in a rounded rectangle) Backend-specific improvements ----------------------------- cairo-drm This is a new, direct-rendering backend that supports Intel graphics chipsets in the i915 and i965 families. It's still experimental and will likely remain that way for a while. It's already got extremely good performance on the hardware it supports, so if nothing else provides a working proof and performance target for the cairo-gl work for Intel graphics. cairo-gl Start using GLSL to accelerate many operations. Many thanks to Eric Anholt and T. Zachary Laine for this work. For the first time, we have what looks like what will be a very compelling OpenGL-based backend for cairo (in terms of both quality and performance). See this writeup from Eric for more details on recent progress of cairo-gl (which he presented at FOSDEM 2010): http://anholt.livejournal.com/42146.html cairo-image The image backend is made dramatically faster (3-5 times faster for benchmarks consisting primarily of glyph rendering). cairo-quartz fixes: Many fixes from Robert O'Callahan and Andrea Canciani including: Fixed gradient pattern painting Improved A8 image handling Fixes for "unbounded" and other compositing operators cairo-pdf fixes: Improvements to embedding of JPEG and JPEG2000 data. cairo-ps fixes: Fix printing of rotated user fonts. Snapshot 1.9.4 (2009-10-15) =========================== API additions: cairo_meta_surface_create() cairo_meta_surface_ink_extents() Finally exporting the internal meta-surface so that applications have a method to record and replay a sequence of drawing commands. cairo_in_clip() Determines whether a given point is inside the current clip. ??? Should this be called cairo_in_paint() instead? in-clip is the test that is performed, but in-paint would be similar to in-fill and in-stroke. New utilities: cairo-test-trace A companion to cairo-perf-trace, this utility replays a trace against multiple targets in parallel and looks for differences in the output, and then records any drawing commands that cause a failure. Future plans: Further minimisation of the fail trace using "delta debugging". More control over test/reference targets. Backend improvements: xlib Server-side gradients. The theory is that we can offload computation of gradients to the GPU and avoid pushing large images over the connection. Even if the driver has to fallback and use pixman to render a temporary source, it should be able to do so in a more efficient manner than Cairo itself. However, cairo-perf suggests otherwise: On tiny, Celeron/i915: before: firefox-20090601 211.585 after: firefox-20090601 270.939 and on tiger, CoreDuo/nvidia: before: firefox-20090601 70.143 after: firefox-20090601 87.326 In particular, looking at tiny: xlib-rgba paint-with-alpha_linear-rgba_over-512 47.11 (47.16 0.05%) -> 123.42 (123.72 0.13%): 2.62x slowdown █▋ xlib-rgba paint-with-alpha_linear3-rgba_over-512 47.27 (47.32 0.04%) -> 123.78 (124.04 0.13%): 2.62x slowdown █▋ New experimental backends: QT OpenVG - The initial work was done by Øyvind Kolås, and made ready for inclusion by Pierre Tardy. OpenGL - An advanced OpenGL compositor. The aim is to write a integrate directed rendering using OpenGL at a high-level into Cairo. In contrast to the previous attempt using Glitz which tried to implement the RENDER protocol on top of OpenGL, using the high-level interface should permit greater flexibility and more offloading onto the GPU. The initial work on the backend was performed by Eric Anholt. Long standing bugs fixed: Self-intersecting strokes. A long standing bug where the coverage from overlapping semi-opaque strokes (including neighbouring edges) was simply summed in lieu of a costly global calculation has been fixed (by performing the costly global calculation!) In order to mitigate the extra cost, the tessellator has been overhauled and tune, which handles the fallback for when we are unable to use the new span rasteriser on the stroke (e.g. when using the current RENDER protocol). The large number of pixel artefacts that implementing self-intersection elimination removes is ample justification for the potential performance regression. If you unfortunately do suffer a substantial performance regression in your application, please consider obtaining a cairo-trace and submitting it to us for analysis and inclusion into our performance suite. Special thanks: To the AuroraUX team for providing access to one of their OpenSolaris machines for cairo and pixman development. http://www.auroraux.org/ Snapshot 1.9.2 (2009-06-12) =========================== API additions: cairo_surface_set_mime_data() cairo_surface_get_mime_data() Should this take unsigned int, unsigned long or size_t for the length parameter? (Some datasets may be >4GiB in size.) Associate an alternate, compressed, representation for a surface. Currently: "image/jp2" (JPEG2000) is understood by PDF >= 1.5 "image/jpeg" is understood by PDF,PS,SVG,win32-printing. "image/png" is understood by SVG. cairo_pdf_version_t cairo_pdf_surface_restrict_to_version() cairo_pdf_get_versions() cairo_pdf_version_to_string() Similar to restrict to version and level found in SVG and PS, these limit the features used in the output to comply with the PDF specification for that version. CAIRO_STATUS_INVALID_SIZE Indicates that the request surface size is not supported by the backend. This generally indicates that the request is too large. CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTED Indicates that a required callback for a user-font was not implemented. CAIRO_STATUS_LAST_STATUS This is a special value to indicate the number of status values enumerated at compile time. (This may differ to the number known at run-time.) The built-in twin font is now called "@cairo:" and supports a limited set of options like "@cairo:mono". Where are these specified? cairo_in_fill() now uses HTML Canvas semantics, all edges are inside. New experimental backends: CairoScript New utility: cairo-trace and cairo-perf-trace cairo-trace generates a human-readable, replayable, compact(-ish!) representation of the sequences of drawing commands made by an application. Under the util/cairo-script directory is a library to replay traces. perf/cairo-perf-trace replays traces against multiple backends and makes useful benchmark reports. This is integrated with 'make perf'. You may collect your own traces or take advantage of traces collected by the community: git://git.cairographics.org/git/cairo-traces (Put this into perf/cairo-traces to run these as part of "make perf".) There is additional WIP in building a debugging tool for cairo applications based on CairoScript (currently very preliminary, mostly serves to show that GtkSourceView is too slow) : people.freedesktop.org:~ickle/sphinx Test suite overhaul: The test suite is undergoing an overhaul, primarily to improve its speed and utility. (Expect more changes in the near future to improve XFAIL handling.) Optimisations: polygon rasterisation! Joonas implemented the Tor polygon scan converter, on typical geometry is about 30% faster for the image backend. Bovine Polaroids! For those not in on the joke, this is the long awaited "copy-on-write snapshot" or "COW snapshot" support. The user-visible feature is that including the same image multiple times into a PDF file should result in only a single instance of that image in the final output. This is unlike previous versions of cairo which would generate very large PDF files with multiple copies of the same image. Adrian says that the PDF is not quite working as well as it should yet, so we hope for futher improvements before cairo 1.10. Bug fixes: EXTEND_PAD. Better handling of large scale-factors on image patterns. Emit /Interpolate for PS,PDF images. Global glyph cache - cap on the total number of inactive glyphs, should prove fairer for fonts with larger glyph sets. Compilation without fontconfig Improved handling of low-bitdepth sources (e.g. copying the contents of 16-bit xserver windows) Regressions: cairo_traps_extract_region >10x slower. Fix pending. Still to come: Region tracking API (ssp) for damage tracking, hit testing etc mime-surface An expiremental OpenGL backend? Tweaks to tessellator, allocations of patterns, delayed initialisation of the xlib backend (reduce the cairo overhead of render_bench by ~80%). |

Update to 1.8.10:
Release 1.8.10 (2010-02-19 Carl Worth <cworth@cworth.org>) ========================================================== The cairo community is pleased to announce the 1.8.10 release of the cairo graphics library. This is the fifth update to cairo's stable 1.8 series. This release consists of about a dozen hand-picked fixes compared to 1.8.8 (which was released about 8 months ago). We recommend that everyone using cairo upgrade to 1.8.10. -Carl General Bug fixes ================= * Fix path construction for the case of cairo_curve_to immediately after cairo_new_sub_path followed at some point by cairo_close_path. (Previously, the final point for the close_path was computed incorrectly.) * Fix for cairo_push_group or cairo_pop_group with a non-empty current path. (Previously the path may have been erroneously translated when either of these functions was called.) * Fix to correctly report an error if cairo_surface_set_fallback_resolution is called with a value of 0 (in either axis). Previously, an assertion would occur later rather than an error being properly reported when the original, invalid value was passed. Bug 23067: Using clear drawing operator crashes printing http://bugs.freedesktop.org/show_bug.cgi?id=23067 * Fix to handle a cairo_arc of radius 0 as equivalent to a cairo_line_to to the center coordinate, (previously cairo would do nothing for a cairo_arc call with a radius of 0). Backend-specific bug fixes ========================== cairo-xlib ---------- * Fix to correctly copy from a Window source. Previously, cairo was failing to include the contents of any sub-windows when copying from a Window source. Bug 12996: Xlib source surface fast-paths do not use IncludeInferiors, while slow paths do https://bugs.freedesktop.org/show_bug.cgi?id=12996 cairo-ft -------- * Fix conversion of freetype index to UCS4 value, (which would previously miss the first character and cause the space glyph to map to 0x00A0 instead of 0x0020). cairo-pdf --------- * Fix Type 1 subsetting to avoid generating corrupt data. Launchpad Ubuntu/cups bug 419143: Printing from evince (and perhaps other GTK apps) to PostScript printers is broken https://bugs.launchpad.net/ubuntu/+source/cups/+bug/419143 * Fix Type 1 subsetting to correctly identify binary eexec data. * Fix Type 1 subsetting to include fixed-content portion in the embedded font, (since some fonts may contain additional PostScript code after the cleartomark). * Fix Type 1 subsetting to append "cleartomark" operator for binary fonts that don't include it. Build fixes =========== * Fix to compile on OpenBSD, (which has a libpng.pc file but none of libpng10.pc, libpng12.pc, or libpng13.pc which cairo was looking for previously). |

Update to 1.8.2:
Release 1.8.2 (2008-10-29 Carl Worth <cworth@cworth.org>) ========================================================= The cairo community is pleased to announce the 1.8.2 release of the cairo graphics library. This is the first update to cairo's stable 1.8 series and contains a large number of bug fixes. It is being released just over one month since cairo 1.8.0. This release consists primarily of bug fixes, but there is one notable new feature, (the ability to build cairo without an external font backend), and there are a few optimizations as well. See below for details on these changes and the most important bug fixes. While many people have contributed to this release, Chris Wilson deserves particular mention. He has contributed well over twice as many changes to cairo since 1.8.0 than everyone else combined. We greatly appreciate the tremendous efforts of Chris and all cairo contributors. We recommend everyone upgrade to cairo 1.8.2 and hope that everyone will have lots of fun with cairo! -Carl New feature ----------- It is now possible to build cairo without any font backend, (such as freetype, win32 or quartz). This is most useful when the application provides custom font rendering through the user-font API. But in the case where no external font backend is available, and no user-font is provided, cairo will render with a failsafe font, (a stroked font covering visible ASCII character). (Behdad Esfahbod) Optimizations ------------- Dramatically speed up compilation with dolt (removes much of the libtool overhead) (Behdad Esfahbod with thanks to Josh Triplett). Several minor optimizations to tessellator (special-cased comparisons, faster insert for skiplist, etc.) (Chris Wilson). Optimize away fractional translation component when doing EXTEND_NEAREST filtering, (for better performance). General bug fixes ----------------- Allow cloning sub-regions of similar surfaces to fix this bug (Chris Wilson): Crafted gif file will crash firefox [XError: 'BadAlloc (insufficient resources for operation)'] https://bugzilla.mozilla.org/show_bug.cgi?id=424333 Fix some matrix confusion to fix this regression (Chris Wilson): Translucent star exports in a wrong way to PDF https://bugs.launchpad.net/inkscape/+bug/234546 Fix some long-standing bugs with respect to properly computing the extents of transformed, filtered surfaces (Owen Taylor, Carl Worth, and Chris Wilson): Bad clipping with EXTEND_NONE http://bugs.freedesktop.org/show_bug.cgi?id=15349 Improve filtering handling in cairo-pattern.c http://bugs.freedesktop.org/show_bug.cgi?id=15367 Many thanks to Chris Wilson for digging out and cleaning up these fixes. Fix compilation on Solaris 10 (Chris Wilson): Cairo requires -DREENTRANT (along with -D_POSIX_THREAD_SEMANTICS) to compile on Solaris 10 with pthreads https://bugs.freedesktop.org/show_bug.cgi?id=18010 Fix very old bug causing dashes to be rendered at the wrong length in fallback images (Adrian Johnson) Dashed strokes too long in fallback images https://bugs.freedesktop.org/show_bug.cgi?id=9189 Fix broken dashing when a dashed path starts outside the clip region (Chris Wilson). Avoid range overflow when computing large patterns (Benjamin Otte and Chris Wilson). Avoid crashing due to an invalid font with an incorrect entry in its CMAP table (Adrian Johnson). Fix bugs in computing maximum size of text requests that can be sent with the Render extension, (avoiding potential crashes when rendering large amounts of text) (Behdad Esfahbod and Chris Wilson). Fix rendering of operators unbounded by the mask (Chris Wilson). Fix compilation on systems without compiler support for a native 64-bit type (Chris Wilson). Fix several cases of missing error-status propagation. (Chris Wilson, doing the work he seems to never tire of). Fix several locking issues found with the lockdep valgrind skin (Chris Wilson). Backend-specific bug fixes -------------------------- xlib: Avoid crash due to attempting XRender calls on pixmaps with formats not supported by the Render extension (Chris Wilson): XRender crashes due to NULL pointer from Cairo on SGI O2 https://bugs.freedesktop.org/show_bug.cgi?id=1173 xlib: Add support for XImages with depth of 4, 20, 24, or 28 bits (Chris Wilson): cairo doesn't support 24 bits per pixel mode on X11 https://bugs.freedesktop.org/show_bug.cgi?id=9102 xlib: Avoid mistakenly considering two surfaces as similar just because their depths match (while their Render formats do not) (Karl Tomlinson). ps: Fix slight mis-scaling of bitmapped fonts (Adrian Johnson) svg: Correctly emit comp-op for paint, mask, and show_glyphs operations (Emmanuel Pacaud). svg: Use finer-grained fallbacks for SVG 1.2 (as PS and PDF backends have been doing since 1.6.0) (Chris Wilson). |
