There are several ways to update a linear screenbuffer, what would be the
fastest method?
a. Drawing direct to screen
b. Drawing to the backbuffer and flipping it
c. Drawing to an area in ram and copying it to screen (32-bit copy).
d. Drawing to an area in ram and copying it to backbuffer (32-bit copy) and
flipping the backbuffer.
e. another method.
