Hm. Good cooperation.

Doesn't it do a selective blit, based on which parts of the screen have
changed? I guess not. But indeed it seems more important to you to get the
code done yourself quickly instead of coming to an agreement with others
concerned.

Do you support resizing the window also when stretched hw blitting isn't
supported? Not everybody has a TNT and dx software stretching is very slow.
Also, if I'd make a game I wouldn't want the user to skew the aspect ratio,
on purpose, or accidently.

Yes, 8 bit mode in a window is very nasty to get right. The first 10 & last
10 colors of the palette are locked as system colors. (You can get around
that in Win95/98, but not in NT I think). I have an idea about a solution
for that, but I don't feel much like putting energy in discussing solutions
anymore.

Seems something's wrong with the clipper.

have fun,
