Right.  That wasn't expected to help this.  That one is still about GDI
drawing, not GL/D3D drawing.

The display link might form the basis of a future timer-based flushing
mechanism, though.  However, that would require multi-thread GL access which in
turn requires either synchronization or render-to-texture and shared contexts.
