force a wglFinish after each device->Clear

The issue seems to be related to clears and draws to render targets, made by
different threads, happening in the wrong order. As the problem is caused by
the GL commands order of execution on the card, different drivers/video
cards/settings, or even different executions of the game make the problem
manifest itself more or less strongly, or not at all.
The attached patch seems to improve things in some cases, but almost surely
it's not a real solution (for sure I expect a small performance hit, however).
Can you give it a try?
