Changes since previous OS4Depot release:

- When the OS3.2 V47 picture.datatype is in use, decoding speed will now be
10-30% faster for RGB, palette based and bitmap images on    both 68k and
- When the OS4 V54 picture.datatype is in use, decoding speed will now be 5-40%
faster for RGB, palette based and bitmap images.  
- Significantly reduced memory usage when decoding 24-bit RGB images, if using
the OS3.2 V47 or OS4 V54 picture.datatype.  
- Fixed crash on OS3 when using picture.datatype V44+.  
- Tweaked version string so that CPU information can be viewed with the version


 - Handles Adobe Photoshop® 2.5, 3.0, 4.0, 5.0 and 6.0 images
   (currently does not support layered images)

 - Most of the available modes are supported, including 24-bit RGB,
   Greyscale, Monochrome, 256 colour palette-based and CMYK images.
   Images using RLE compression are also supported

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

 68k version

 - Kickstart 3.0 or higher
