65a7b19f40 Make each OS window have its own framebuffer 
This commit fixes graphics rendering when more than one OS window is
open, all OS windows are semi-transparent, and multiple windows contain
graphics.

This commit closes #2310.

b8acb9b133 Pass cell data to GPU directly 
Converts update_cell_range() to a simple memcpy(). The GPU has to do
roughly the same amount of work (there is one extra attribute, and one
extra calculation for reverse video).
