Fixes for gcc 3.4
-----------------
Fix prototype mismatches so that cairo can be built by gcc 3.4.
Updates to track glitz
----------------------
Various fixes to support the latest glitz snapshot (0.1.2).
Gradient updates
----------------
Radial gradients now support both inner and outer circles.
Transformed linear gradients are now properly handled.
Fixes for extend type reflect.
Glitz updates
-------------
Converted shading routines to use fixed point values and introduced a
shading operator structure for more efficient shading calculations.
Support compositing with mask surface when mask is solid or
multi-texturing is available.
PNG backend cleanups
--------------------
Fix output to properly compensate for pre-multiplied alpha format in cairo.
Add support for A8 and A1 image formats.
Bug fixes
---------
Avoid crash or infinite loop on null strings and degeneratively short
splines.
New? bugs in cairo_clip
-----------------------
There are some fairly serious bugs in cairo_clip. It is sometimes
causing an incorrect result. And even when it does work, it is
sometimes so slow as to be unusable. Some of these bugs may not be
new, (indeed cairo_clip has only ever had a braindead-slow
implementation), but I think they're worth mentioning here.
* Cairo was updated to track the changes in libpixman, and now depends
on libpixman version 0.1.1
Changes 0.1.21:
* New OpenGL backend
* Automatic detection of available backends
Changes 0.1.20:
* New pattern API
* Update to XCB backend
* Faster clipping
Includes new functions:
- cairo_current_path, cairo_current_path_flat,
cairo_surface_get_filter. Support for XCB backend. Fixes for
building in cygwin. Adds cairo_surface_get_filter.
Cairo is a vector graphics library with cross-device output support. Currently
supported output targets include the X Window System and in-memory image
buffers. PostScript and PDF file output is planned. Cairo is designed to
produce identical output on all output media while taking advantage of display
hardware acceleration when available (eg. through the X Render Extension).
Cairo provides a stateful user-level API with capabilities similar to the PDF
1.4 imaging model. Cairo provides operations including stroking and filling
Bezier cubic splines, transforming and compositing translucent images, and
antialiased text rendering.
