Turn off desktop compositing in Windows ("Aero") for Radiant.

Browse source 
Otherwise, "hall of mirrors" effect takes place in the OpenGL viewports.
This fix is a real hack.  It's actually borrowed from other Radiants such
as NetRadiant.  I'd like to fix the underlying issue someday so that Aero
can be used with Radiant.

Rambetter on Fri Jan 21, 2011:
People with recent NVIDIA cards and Windows 7 (Aero) are complaining about "hall of mirrors"
effect in the OpenGL viewports. The code below is borrowed from NetRadiant to address
this issue. This change turns off desktop compositing (globally) while Radiant is running.
It's a real hack but the "correct" fix is very involving, so until the underlying problem
is addressed we need this code here. I don't know for sure what the underlying problem is,
but I have a hunch it's the version of gtkglext.dll we're using.
