[compiz] compiz swapbuffers patch

[Brandon Wright]

Hi Jesse,

I've looked at your patch, and it won't work normally unless the whole
screen is damaged. I assume you're running a plugin that does this by
default, and that's why you missed it. In any case, you need a couple
extra lines. Something like:

if (alwaysSwap == TRUE)
    damageScreen (s);

at src/screen.c:1455 in the original file, or just after the whole "if
(s->slowAnimations)" block.

Good luck getting this patch in. Compiz has needed something like this
for a while.
