[PATCH 14/15] wined3d: Add device->isInDraw checks in LoadLocation.

[Alexander Dorofeyev]

Oh, you are right. Must be fixed some other way then, I guess, maybe moving 
assignment to isInDraw lower or moving ActivateContext higher. From what I 
understood from Bioshock bug (http://bugs.winehq.org/show_bug.cgi?id=9973), 
moving ActivateContext in drawPrimitive produces bugs in other programs, right? 
Could you add to that bug a short description of what games etc needed to 
reproduce these problems?
