Description
I had a sudden flash of inspiration about the Kyra CD intro glitch, where the image goes almost black at the beginning of the "tree2" movie.
Since each new frame is XOR:ed with whatever was there before, the screen going black would mean that the decoded frame data looks just like what's already in the destination buffer. So to keep that from happening, all we have to do is to make sure the buffer is cleared first.
I don't know if this patch represents the correct way of doing that, though. But it does fix the aforementioned glitch for me.

LordHoto, you took this item -- now, is there any reason you didn't just apply it? If so, please add them to this tracker item.

Actually, I assigned it to him, then spoke to him in private. He promised to take a closer look in a few days, when he was less busy.
I'm convinced that I've found the reason for the CD intro glitch, but I have no idea if this is the correct fix for it. It might break the floppy version, which I do not have myself so I can't test.

ok commited, but with one change: it clears the screen page only if it is a CD version, since if it would be done like you did it we have the same glitch with the floppy version. thanks
