 Program information
 -------------------
 akGIF.datatype is a GIF datatype, which supports GIF87a/89a and
 handles transparency along with tiled images - the latter either
 as multiple frames (single pictures instead of an animation),
 8 bit "mosaic" (if same palette for all tiles) or 24 bit "mosaic"
 (if different palette for some tiles - this results in a so-called
 "true-color GIF").

 It does support interlaced GIF (note: it reads interlaced GIF, but
 DataTypes cannot display images progressively - instead only as a
 single chunk). The same restrictions apply to tiled images.

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

 --------------------------------------------------------------------------

 You should use the included preferences program for best configuration.

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

 V45.90 (13.9.2008):  - updated TestDTAlpha tool and check for
                        PICDTALPHA
                      - added STRIPALPHA description to .guide

 V45.87 (16.1.2008):  - fixed version/date strings for V45.86
                      - for tiled images now also other types
                        of transparency/alpha are supported:

                         - 24 bit GIF (multi-palette) tiles
                           single/multi color transparency becomes
                           32 bit ARGB/RGBA
                         - 8 bit GIF multi color transparency
                           becomes 32 bit ARGB/RGBA in case
                           TRANSTOALPHA is set (otherwise ignored,
                           since it is not clear which of the
                           different transparent colors should
                           be made transparent in the single
                           color 8 bit case)
                      - added STRIPALPHA option
                      - fixed minor mem-leak related to extra
                        buffers for alpha and alpha-mapped
                        transparency
                      - fixed newly introduced race condition
                      - avoid multiple level 2 buffering setup
                      - fixed the viewmode fix from V45.86
                        a second time
                      - MOS: switched compiler (same as SV5)
                             and enabled optimizer

 V45.86 (5.1.2008):   - fixed bug in TRANSTOALPHA (oops)
                      - fixed long-standing MOS bug in viewmode
                        generation routine (did not occur with 68k
                        and did only pop up with some graphics)

 V45.85 (4.1.2008):   - MOS/68k: now really building from same
                                 source tree; the following
                                 information is relative to
                                 the former MOS tree
                      - improved MOS startup code
                      - added TRANSTOALPHA and SWAPALPHA options
                      - documented all prefs settings again
                      - Prefs: made the labels easier to understand,
                               especially the 24 bit / tile settings

 V45.84 (2.1.2008):   - some additions to asyncio routines
                      - improvements in asyncio routines

 V45.83 (28.12.2007): - fixed bug in asyncio dispatcher, which
                        could have lead to a stale file lock,
                        thus memory loss, in case of DOS fallback
                        during AsyncIO availability
