-Improve API by hiding the png_struct and png_info structs.
-Finish work on the no-floating-point version (including gamma compensation)

 Better C++ wrapper/full C++ implementation?
 Fix problem with C++ and EXTERN "C".

 Add "grayscale->palette" transformation and "palette->grayscale" detection.

 Multi-lingual error and warning message support.
 Complete sRGB transformation (presently it simply uses gamma=0.45455).
 Man pages for function calls.

-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.
