Release Notes
V43.757
o fixes some trouble with crashes on certain machines
V43.755
o new pcdt prefs program v43.3 included. It also works now when the v43
picture.datatype is actually not running
o new sub classes included
o added stack swapping code to picture.datatype dispatcher in order to fix
stack overflow related problems with applications which do not allocate
enough stack space
V43.754
o fixed some bugs in method DTM_DRAW
o fixed some problems in conjunction with halfbrite source data
o new gif.datatype 43.14 included
V43.753
o new pcdt prefs program v43.2 included
o the preferences file now has moved to env:sys
o new gif.datatype 43.13 included which fixes some strange crash problems
o fixed some problems in conjunction with planar graphic formats which
occasionally led to strange looking mwb-patterns
V43.751
o the public semaphore is now available even if the picture.datatype is
expunged. This fixes a severe crash when the library is expunged
V43.750
o fixed a BYTE-READ from $0 when non v43 compatible applications called the
picture.datatype
V43.748
o gtlayout.library included in this archive. (required for the prefs
program)
o The application list which contains all V43 compatible applications may
now be configured with a seperate prefs program.
o removed support for environment variable "cybergraphics/pcdt_dither"
Please use the supplied prefs program PCDT to change dither settings now
o the expiration time is now 4 month instead of 1 month. So users who
can not access the net but get the datatype from an aminet cd are able
to use the picture.datatype release for a certain amount of time
until a new version is released

also includes a backup option
o Tower JPEG Codec Class included as seperate archive
o new gif.datatype sub class V43.12 included

o the picture.datatype now uses ordered dithering as default.
A switch to select between floyd or ordered may follow in the
