 Program information
 -------------------
 This datatype supports reading of SGX Graphics Files, which is
 SView-Library's (deprecated) own 8/24/48 bit graphics file format
 with LZ77 compression support. Alpha channel (32/64 bit) is supported
 in V43 mode. The internal precision of the file format allows
 for 8 and 16 bit per channel (24/48 bits per pixel) - currently
 this is always scaled down to 8 bit prior to datatype export.

 SGX means "SView Graphics". SGX was the predecessor of IFF-RGFX.
 Older verions were named "SVG" and did support XPK (both changed).

 It is a very fast, smart and amiga-based alternative to other
 non-lossy 8/24/48 Bit file formats (surely IFF-RGFX is even smarter).

 Includes: - Conversion tool "AnyToSGX" for conversion DT->SGX
             (with V43 support for 24 Bit conversion)

 WARNING: if the pic-dt of your OS version does not support alpha channel
          handling, then always set STRIPALPHA=ON (no ARGB/RGBA)

 You should use the included preferences program for best configuration.

**************************************************************************

 V45.92 (5.4.2009):    - added support for new SGX sub-type (LZ77)
                       - removed spec (separate archive)
                       - fixed some bugs (also in AnyToSGX)
                       - AnyToSGX now only writes SGX sub-type

 V45.91 (18.3.2008):   - fixed possible blitter race condition
                         in Any2SVG (when handling DT images with
                         depths <= 8 bit)
