Log Message:
-----------
Revert a commit from 5 years ago that added a glFinish call before swapping on
Windows. This is really bad for performance and especially showed in the game
engine. The purpose was to disable FSAA and fix some UI issue on Geforce 2
graphics cards, hopefully the drivers have been fixed by now? I have no way to
test this, so we'll see if an issue pops up on those older cards, and a lot of
code changed since then anyway so it might not even be needed anymore.
