 TODO - list of things to do for libpng:
 
 Final bug fixes.
-Fix problem with C++ and EXTERN "C".
+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?
-Keep up with public chunks.
-sPLT chunk handling.
+Fix problem with C++ and EXTERN "C".
 cHRM transformation.
-Support for application-defined chunk handlers.
 Improve setjmp/longjmp usage or remove it in favor of returning error codes.
-High-level API for reading images.
 Add "grayscale->palette" transformation and "palette->grayscale" detection.
-Color to gray transformation.
 Improved dithering.
 Multi-lingual error and warning message support.
 Complete sRGB transformation (presently it simply uses gamma=0.45455).
@@ -18,7 +15,10 @@ Man pages for function calls.
 Better documentation.
 Better filter selection
    (counting huffman bits/precompression?  filter inertia?  filter costs?).
-Optional palette (sPLT) creation.
 Histogram creation.
 Text conversion between different code pages (Latin-1 -> Mac and DOS).
-Improve API by hiding the info_ptr.
+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).
+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.
