[WIN32K]
 - Properly send WOC_RGN_CLIENT to the GDI driver when window client region changes
 - Increment CLIPOBJ::iUniq so that drivers know that something changed
 - Some improvements in win32k side of opengl pixel format selection
 - Hack around atom collision between the kernel atom table and the win32k one
Now vmware ICD does something decent, even if you can use it only once per ReactOS session (!)
