i've setup a window on the screen and would like to update the window
region (visible region) by first drawing what i need to an off-screen port
(i don't know if i mean grafport, region, etc) and then copy that to the
GrafPort of the window. i can't figure out how to do this. all i'm drawing
to the port is character data. how can i tell quickdraw to draw off-screen
(which i want because it's faster) and then copy it to my windows GrafPort?
