Is is possible to double-buffer GEM graphics on the ST?  My needs are
relatively modest:  I would like to use the ordinary GEM graphic routines,  
but have them "draw" to a screen buffer (not to the active buffer (and hence
the display screen)).

After the drawing is complete, I want to make the screen buffer the active
buffer, effectively blasting the graphics to the screen.

Can this be done?



Thanks in advance,
