Changes since previous Aminet release:

 - Fixed crash in 68020 and 68030 builds.


FEATURES

 - Handles both lossless WebP and lossy WebP images

 - Different modes for handling alpha channels / transparency

 - Highly optimized datatype dispatch engine and WebP decoder,
   resulting in a very efficient, compact and quick WebP 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 libwebp 1.2.4.
