If you're willing to run in EGA mode, you can "redisplay" images quickly and
very easily.  In EGA mode there are multiple pages, only one of which is 
active.  While the active page is being displayed, you can draw to a 
non-active page.  Once the drawing's done, you can "flip" the pages, making
the non-active page active (hence visible on the screen).

Anyway this is a common way to do animation.  Unfortunately TP does not
support multiple pages for VGA or SVGA.
