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

 - PowerPC support with native OS4, WarpOS and MorphOS versions

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