Changes since previous Aminet release:

 - Updated with libpng 1.6.39 and zlib 1.2.13.


FEATURES

 - Supports both normal and interlaced PNG files

 - Gamma correction options allow the output image to be changed to
   suit your monitor/environment

 - Alpha channel handling can be configured to output RGBA bitmaps, or
   RGB bitmaps either by combining the alpha information internally
   using a configurable background colour or simply stripping it

 - Highly optimized datatype dispatch engine, and fast PNG decoder,
   resulting in a very efficient, compact and quick PNG datatype

 - Asynchronous file i/o and double buffering techniques (WarpOS only),
   which speeds up image decoding
 
 - Optimized versions for 68020, 030, 040 and 060

 - PowerPC support with native OS4, WarpOS and MorphOS versions

 - Alter the pen allocation precision when images are remapped to an
   8-bit display

 - Specific support for the AmigaOS picture.datatype v44+, when available

 - The dithering feature of the AmigaOS picture.datatype v44+ can be
   configured to your liking (e.g. disabled for 15/16-bit displays)

 - Based on libpng 1.6.39 and zlib 1.2.13
