2TODO - list of things to do for libpng:
3
4Final bug fixes.
5Better C++ wrapper/full C++ implementation?
6Fix problem with C++ and EXTERN "C".
7cHRM transformation.
8Remove setjmp/longjmp usage in favor of returning error codes.
9Palette creation.
10Add "grayscale->palette" transformation and "palette->grayscale" detection.
11Improved dithering.
12Multi-lingual error and warning message support.
13Complete sRGB transformation (presently it simply uses gamma=0.45455).
14Make profile checking optional via a png_set_something() call.
15Man pages for function calls.
16Better documentation.
17Better filter selection
18 (counting huffman bits/precompression? filter inertia? filter costs?).
19Histogram creation.
20Text conversion between different code pages (Latin-1 -> Mac and DOS).
21Avoid building gamma tables whenever possible.
22Use greater precision when changing to linear gamma for compositing against
23 background and doing rgb-to-gray transformation.
24Investigate pre-incremented loop counters and other loop constructions.
25Add interpolated method of handling interlacing.
26Switch to the simpler zlib (zlib/libpng) license if legally possible.
27Extend pngvalid.c to validate more of the libpng transformations.
