I think you're wrong there, Rick. (Gee I never thought I'd get to say
that!) XINTERANIMATE generates off-screen pixmaps and then brings them
onto the screen with DEVICE, COPY=... and this is faster than calling
TV for every frame.

So, as Reimar suggested, Dan should definitely check out
XINTERANIMATE.
