The problem with the proposed scheme is that it wins you little over
the current scheme.  Blitting images is not done on a line by line
basis - if it were, the blit might be a little cleaner, but would be
one hell of a lot slower, as the overhead involved in setting up the
blitter for each line transfer would be immense.  Making CHIP RAM out
of 60ns chips and doubling the blitter's transfer rate would help a lot
more...  at a price.
