To address that, in 8bpp it's really not too much
of an issue, but for higher modes the system is mostly
unusable without scrolling and filling. It's not
a question of the efficiency of the code (i.e., having
a JIT wouldn't help). The problem is the readback speed
on the VGA card, which nails you when you're doing
software scrolling. I can read from my 5400rpm disk
faster than I can read from my VGA memory.
