[comp.sys.mac.misc] Switching color graphic screens

=================================================================
What I want to know how to do is to write off screen to a color graph
port (actually several of them) and then rapidly bring the images on
the main window.  Ideally, I'd like to use animated colors so that I
have exact control of the colors.  The off-screen graph ports could
have small color tables (2 or 3 bits) to save memory.  I'd like the off
screen graph ports have the same palette (color tables).  I am
programming in Lightspeed Pascal.
