Add new BGE Stereo mode: 3DTV top-bottom. 

This mode is designed for passive 3D TV: the viewport is split
horizontally - left eye above, right eye below - but the original camera
viewport is squashed in each half (with half the vertical resolution).
This is necessary to restore the aspect ratio in the 3D output because the TV expands each half to the full screen size.
