NEW FEATURES

This update provides several enhancements and/or corrections over
previous releases:

1) "AnimGIF - Load Anim-Brush" used to require a double-buffering screen
   mode to create the animation. This is the standard for proper Amiga
   animation, but Personal Paint has always been strong in supporting RTG
   animation without double-buffering. This has been extended to this
   script.

2) "AnimGIF - Save Anim-Brush" allows for the anim-brush transparency
   to be set or cleared directly from the user interface of the Rexx
   script. Additionally, the timing of the anim-brush frames can be
   copied from the timing of the frames in the current animation.

3) On some web browsers, GIF animations using transparency effects would
   be displayed differently (e.g. leaving "trails") than with Personal
   Paint. This was caused by the lack of a clear specification on the
   various frame disposal methods which can be employed for GIF
   animations if transparency is used. The update contained in this
   archive was designed to offer a better compromise between optimization
   and compatibility with different de facto standards. Version 5.4
   solves a potential problem with multiple-palette animations when viewed
   with older versions of certain PC browsers.

This archive does not contain, create or modify any GIF code. Only some
animation features are updated. The installation procedure requires the
personal_gif_io.library (version 5.1, 5.2 or 5.3) to be already installed
in the system. These libraries (or newer ones) are included with the
commercial distribution of Personal Paint 7.

These are some examples of file sizes of famous GIF animations taken from
the Internet and saved again with Personal Paint 7 and this update:
