Up until now I have been accomplishing the above monstrocity(see Subject-
Line), by creating my own views, viewports, bitmaps, rastports, and rasinfos,
however, now the need has arisen to make this neat display work under intuition
(i.e. be able to pull the thing down, like an intuition screen, that's it).
I have the code posted by Rob Peck demoing Intuition dual-playfield,
and it takes care of the dual-playfiels part. I also have opened overscan
intuition screens. The delema seems to be that I can't do the
ViewPort swap trick that I was doing without intuition.
I just read the reply made to the question about double buffering, and I
will try that when I get home. Maybe that'll do it.
Jim.
