A clarification:
Not quite. The general idea will be to have a "CreatePixmap"
routine
: that will basically allocate memory, and then the returned id can be used
for
: any of the drawing functions. All drawing will be offscreen.
I mean here that all drawing to the returned id from CreatePixmap
will
be offscreen. Of course, normal window drawing will be onscreen for the
unclipped
portions of the window.
Then, when
: the contents want to be displayed, a "BitBlit" routine will copy some
x,y,w,h
: portion of the offscreen bitmap to a specified window on the screen.
