Yeh, well, then doublesize the graphics - 640x480 is the standard lowend PC resolution - you don't want to run the risk of blowing some peoples monitors up.
Also if you're in windowed mode (ie with the desktop in the b/g) there is no such thing as a backbuffer, all drawing operations are instantaneous. Altho I -think- it works differently in a canvas..?
