version 1.2.37beta01 [May 14, 2009]
Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36. The
memset() was using "png_ptr->rowbytes" instead of "row_bytes", which
the corresponding png_malloc() uses (Joe Drew).
Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri)
Updated some of the makefiles in the scripts directory (merged with
those in libpng-1.4.0beta57).
version 1.2.37beta02 [May 19, 2009]
Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG)
Relocated misplaced #endif in pngwrite.c, sCAL chunk handler.
Conditionally compile png_read_finish_row() which is not used by
progressive readers.
Added contrib/pngminim/preader to demonstrate building minimal progressive
decoder, based on contrib/gregbook with embedded libpng and zlib.
version 1.2.37beta03 [May 20, 2009]
In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
is only one makefile in those directories, and revised the README files
accordingly.
Reformated sources in libpng style (3-space indentation, comment format)
version 1.2.37rc01 [May 27, 2009]
No changes.
versions 1.2.37 and 1.0.45 [June 4, 2009]
Reformatted several remaining "else statement;" and "if () statment;" into
two lines.
Added "#define PNG_NO_WRITE_SWAP" to contrib/pngminim/encoder/pngusr.h
and "define PNG_NO_READ_SWAP" to decoder/pngusr.h and preader/pngusr.h
Added sections about the git repository and our coding style to the
documentation (merged from libpng-1.4.0beta62)
Added a section about using png_get_io_ptr() in configure scripts to detect
the presence of libpng.
Update provided by Hasso Tepper on pkgsrc-users.

- Don't take new photo while waiting for the previous
Ignore new photo requests if we are still waiting for an "handoff"
signal for the previous one, fixes bug #582902
- Fix a couple of trivial memory leaks in the thumbnail generator code, fixes bug #578289
- Don't return if "image-loading" icon is not found, we will have an empty
pixbuf while the thumbnail thread is running but it is surely better than
no thumbnail at all. Try to fallback to generic "image" icon before giving up,
fixes (at least it should) bug #582240.

matplotlib is a pure python plotting library designed to bring
publication quality plotting to python with a syntax familiar to
matlab users. A lot progress towards this goal has been made since
the first release of matplotlib, the library does produce high quality
2D plots. All of the plotting commands can be accessed either via a
functional interface familiar to matlab users or an object oriented
interface familiar to python users, and several high resolution output
formats are supported.
This package contains the Tk driver for matplotlib.
Tutorial: http://matplotlib.sourceforge.net/tutorial.html
* Defined TOO_FAR == 32767 in deflate.c (again). The definition
has continually been inadvertently omitted during zlib updates
since pngcrush version 1.6.4.
* Revised handling of xcode files so at least we can get printout
of IHDR values with "pngcrush -fix -n -v xcode.png"
Changes 1.6.16:
* Added -newtimestamp and -oldtimestamp options and changed
default condition to timestamping the output file with
the current time (i.e., -newtimestamp is default)
* If the -oldtimestamp option is used then the output file
has the same timestamp as the input file.
* Added CgBI chunk detection.
Changes 1.6.15:
* Fixes some missing typecasts on png_malloc() calls, patch from
an anonymous reporter to the SourceForge bug tracker.
* Added -time_stamp option to change time stamping from default
condition.

0.1.9
------------------------------------------------------------------------
Added Leica RWL raw format in list of supported files.
Updated to LibRaw 0.7.2 :
- More accurate types conversion in libraw_datastream.h to make compilers happy.
- New postprocessing parameter auto_bright_thr: set portion of clipped pixels for
auto brightening code (instead of dcraw-derived hardcoded 1%).
- '-U' option for dcraw_emu sample sets auto_bright_thr parameter.
Updated to LibRaw 0.7.1 :
- Fixed broken OpenMP support.
Updated to LibRaw 0.7.0 :
- Black (masked) pixels data extracted from RAW and avaliable in application.
- Application can turn off RAW data filtering (black level subtraction,
zero pixels removal and raw tone curve).
- New 'input framework' released. Reading raw data from file and memory buffer supported from scratch.
LibRaw-using application can implement own data reading functions (e.g. reading from network stream).
- Fuji SuperCCD: raw data extracted without 45-degree rotation.
- New sample applications: 4channels and unprocessed_raw.
- Imported (subsequentally) new dcraw versions from 8.89 to 8.93 (up to date)
Updated to libraw 0.6.15:
- more accurate pentax dSLR support
- fixes in Kodak 620x/720x identification
- faster identification procedure for some formats.
- Fixed bug in custom gamma curve creation
Updated to libraw 0.6.14:
- user-specified gamma curve.
- Pentax K2000/Km support.
- Changes in Canon sRAW processing (support for 5D2 fw 1.07).
version 1.2.36beta01 [February 28, 2009]
Revised comments in png_set_read_fn() and png_set_write_fn().
Revised order of #ifdef's and indentation in png_debug definitions of png.h
bug introduced in libpng-1.2.34.
version 1.2.36beta02 [March 21, 2009]
Use png_memset() after png_malloc() of big_row_buf when reading an
interlaced file, to avoid a possible UMR.
Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users
having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined.
Revised libpng*.txt documentation about use of png_write_flush().
Removed fflush() from pngtest.c.
Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h
version 1.2.36beta03 [March 27, 2009]
Relocated misplaced PNG_1_0_X define in png.h that caused the prototype
for png_set_strip_error_numbers() to be omitted from PNG_NO_ASSEMBLER_CODE
builds. This bug was introduced in libpng-1.2.15beta4.
Added a section on differences between 1.0.x and 1.2.x to libpng.3/libpng.txt
version 1.2.36beta04 [April 5, 2009]
Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles)
version 1.2.36beta05 [April 24, 2009]
Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
application code writers to bypass the check for multiple inclusion
of setjmp.h when they know that it is safe to ignore the situation.
Made some cosmetic changes to whitespace in pngtest output.
Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress
"shadowed declaration" warning from gcc-4.3.3.
Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
warning about a global "gamma" variable in math.h on some platforms.
version 1.2.36rc01 [April 30, 2009]
No changes.
version 1.0.44 and 1.2.36 [May 7, 2009]
No changes.
GooCanvas 0.14 (Mar 15 2009)
==============
o Added support for tooltips (this means we need GTK+ 2.12).
(Note that there is a GTK+ bug which will cause problems with
tooltips on a large canvas. See bug #573294.)
o Added "x", "y", "width" and "height" properties to items that
didn't have them.
o Fixed bug in goo_canvas_convert_from_item_space().
o Added "scroll-event" signal to GooCanvasItem.
GooCanvas 0.13 (Nov 30 2008)
==============
o New GooCanvasGrid item for drawing grids on the canvas.
o Support for static items that don't move as the canvas is zoomed
and scrolled (this is a bit experimental).
o Font hinting is not turned off any more - this means smaller text should
be more readable. Hopefully it doesn't affect text layout.
o Fixed a few GooCanvasTable drawing bugs.
o Fixed GooCanvasText drawing, when align is set.
o Fixed GooCanvasPolyline is_item_at() code, so the fill isn't tested.
o Added "animation-finished" signals to GooCanvasItem & Model.
