Enable DWM transparency for OpenGL windows under Windows
Starting with Windows Vista, we can control the compositing window
manager using the DWM APIs. This allows us to make truly transparent
OpenGL windows.
We also have to detect and listen if compositing is enabled, otherwise
enabling transparency will cause glitches all over the place.
This (partially) fixes
