overview
-----------------------------
  - guigfx.library is an application layer for pixel graphics.
  - guigfx.library breaks the chains of all those nasty
    planar, chunky, 8/16/24bit, OS3.0, OS3.1, OCS, ECS, AGA,
    CybergraphX and Picasso96 considerations.
  - with guigfx.library you no longer have to take care about your
    application running on a OCS machine or on a high-end
    graphics-card system.
  - guigfx.library lets you freely choose truecolor graphics for
    your applications.
  - with guigfx.library your graphics will always look as fine as
    possible, on any screen, no matter if driven on 24 bit
    1024x768 CybergraphX/Picasso96, on HAM8, or 1 bit productivity
    interlaced.
  - guigfx.library does quick color-reduction, rendering,
    remapping and dithering for you. only you don't know when,
    on which machine, under what circumstances.
  - guigfx.library treats scaling as a standard operation.
    it is available at any time, without extra consideration,
    without extra memory consumption, even without a true loss
    of performance.
    
  - guigfx.library handles screen pen allocation in an extremely
    effective way.
  - guigfx.library hides bugs, incompatibilities and insufficiencies
    of graphics.library, cybergraphics.library and Picasso96 from
    you. it is an attempt to render incompatibilities between
    different versions of CybergraphX and Picasso96 obsolete.
    
  - guigfx.library features picture.datatype import. standard and
    v43 (including Picasso96) picture datatypes are automatically
    recognized and used as available.
  - guigfx.library does not call SetFunction() and is hereby
    guaranteed to never do so in future versions.
  - guigfx.library puts all that stuff into a black-box,
    freeing your mind for the creative part.

recent changes
-----------------------------
v20.1   [05-Nov-11]
        - for some reason the only build for 68k I included in the release on
          16-Mar-05 was a build for systems with an FPU. Even worse, I didn't
          mark it as such which caused lots of confusion with people trying to
          use it on non-FPU systems. I have now added 68k builds for all 
          architectures that were originally part of the guigfx distribution
          (020, 040, 060, FPU). Thanks to Niels Schapke for reporting this problem.
        - bumped the version because the 68k builds now also contain the
          WritePixelArray() fix from v20.0.2 (which should have been v20.1
          back then already instead of that awkward non-standard versioning,
          sorry!)
        - removed the MorphOS build because guigfx.library is part of MorphOS    
        
v20.0.2 [16-Mar-05]
	- fixed wrong modulo value in two WritePixelArray() calls; fixed
	  only in the OS4 version as the wrong value is harmless under
	  MorphOS and OS3.x. Reported by Stephan Rupprecht.
	    	   
v20.0   [03-Mar-05]
        - added AmigaOS 4 binary and includes
------ all releases after v20.0 made by Andreas Falkenhahn <andreas@airsoftsoftwair.de> ------
      
v20.0
	- added picture attributes PICATTR_NumPaletteEntries and
	  PICATTR_Palette to GetPictureAttrs(). This way you can
	  query a picture's palette. PICATTR_NumPaletteEntries will
	  currently always return 256 if a picture is palette-based,
	  and zero otherwise. PICATTR_Palette expects a buffer of
	  256 ULONG entries in (by default) the format PALFMT_RGB8.
	  Requested by Andreas Falkenhahn.
	  
v19.2
        - when a picture was read from a hicolor/truecolor rastport
          using ReadPicture(), a palette was incorporated to the picture.
          ClonePicture() created a copy of that palette but did not
          actually place it in the resulting picture. when the library
          was closed, the leak was indicated with a ILLEGAL exception.
          fixed.
v19.1
	- fixed a LOOONG standing bug when adding pictures to
	  a pensharemap, when the picture was less than 7 lines
	  high. ouch!
