Attempted fix for #27482: game engine running slow due to revision 36698 which
fixed frame colors for letterbox drawing (happens when in camera view).
Cause is unclear, seems some sort of strange graphics driver thing on 32 bit.
Changes are a fix for the incorrect usage of glViewport, and avoiding the extra
clear if it's not needed.
