TODO - list of things to do for libpng:
Final bug fixes.
@@ -17,9 +18,14 @@ Better filter selection
(counting huffman bits/precompression? filter inertia? filter costs?).
Histogram creation.
Text conversion between different code pages (Latin-1 -> Mac and DOS).
Should we always malloc 2^bit_depth PLTE/tRNS/hIST entries for safety?
Build gamma tables using fixed point (and do away with floating point entirely).
Avoid building gamma tables whenever possible.
Use greater precision when changing to linear gamma for compositing against
background and doing rgb-to-gray transformation.
Investigate pre-incremented loop counters and other loop constructions.
Add interpolated method of handling interlacing.
Provide for conditional compilation of 16-bit support (except for the
initial stripping down to 8-bits when reading a 16-bit PNG datastream).
Switch to the simpler zlib (zlib/libpng) license if legally possible.
