CLOANTO SOFTWARE UPDATE


THIS ARCHIVE CONTAINS THE LATEST VERSION OF THE FOLLOWING LIBRARIES:

  - personal_agnus_blit.library


PROGRAMS USING THE LIBRARIES:

  - Personal Paint version 7.0 and higher
  - ColorType version 3.1 and higher


INSTALLATION DIRECTORY:

  - Default   : "PPaint:libs", "ColorType:libs"
  - Optionally: "LIBS:"
  (software checks both paths and uses the newer library if two are found)


ENVIRONMENT VARIABLES:

  - PBlit_Agnus (Yes/No/Auto)


NEW FEATURES:

In addition to containing blitting functionality based on the Amiga Agnus
blitter logic, this library is queried on startup by programs like Personal
Paint to determine whether the Amiga (Agnus) blitter is available for use.

Based on the result provided on startup by this library, for example,
Personal Paint might shadow the "Settings/Graphics/Amiga Blitter" option
and automatically use a blitter emulation library instead.

This new library is more flexible in deciding whether it is acceptable to
use the Amiga blitter or not, allowing the user to make a choice in certain
conditions where the previous library would have shadowed this program
option. For example, certain CyberGraphX options which can be set by the
user to use Fast RAM in certain conditions in which the system would
normally use Chip RAM, will not cause the Amiga Blitter option to be
disabled when using this new library. It remains up to the user, when
experimenting with these non-standard system options, to manually disable
the Amiga Blitter in the application if the new system settings cause
incompatibilities.

This library, like the previous versions, contains complex and up-to-date
logic to detect a condition in which it might not be safe to use the Amiga
blitter. This logic can be overridden by setting the "PBlit_Agnus"
environment variable to Yes or No (default = Auto).

Additional functionality has been integrated in this library to better
support future programs.


OTHER NOTES:

As of version 2.0 of the blitting libraries, and up to a 68040 CPU the Agnus
version is on average still faster than the 68K libraries. The Agnus
blitting library can only work with bitmaps in Chip RAM.
