Various game engine fixes:

Browse Source 
* Fix issue with add transparency mode with blender materials.
* Possible fix at frontface flip in the game engine.
* Fix color buffering clearing for multiple viewports, it used
  to clear as if there was one.
* Fix for zoom level in user defined viewports, it was based on
  the full window before, now it is based on the viewport itself.
* For user defined viewports, always use Expose instead of
  Letterbox with bars, the latter doesn't make sense then.
