The faster scrolling is done by copying less memory. The video memory
used for one scan line is 1024 bytes, even in 1-bit mode. But visible
are only 640 bits = 80 bytes. Copying only the visible part of the
screen makes scrolling up to 12 times faster. This is valid for LCII
internal video, other machines might have other values.

I don't know about this is mergable to the grf driver as I use currently
neither dt nor X (slow and small machine).
