=09Hi! I'm working on a interactive program which needs fast drawing.
I'm looking for a way to similate the 'backing store' of Xt. I know that
X Form do have a double buffering, but am not sure if that works for
drawing objects (e.g. fl_polyf()). Since I don't want the sweeping
'effect' happens to my polygon updates. I'm also trying to do that in a
Canvas also, but I have little information/example on that. So, can
somebody here give me some hints on these questions?

=09Thanks for your precious time!
