i set a background pixmap for the drawing_area's window and draw directly
to this pixmap. after drawing, synthesize an expose event (or do the blit
directly).
the X server will now update the window from the contents of the
background pixmap in the fastest fashion whenever your window gets an
expose event (don't know about how gtk on windows(r)(tm) handles this).
after drawing to the pixmap, synthesize an expose event or do the blit
yourself.
have to append my drawing widgets are c++, but the method should work with
python all the same.
