BGE: fix for [#20684] Game Render blanks screen on Anaglyph Stereo view
The problem was: the Blender default camera has DOF distance as 0.0. Since we
are using this as Focal Length for the stereo calculation we had terrible
stereo by default.
Fix: whenever DOF == 0.0 we use focal length as eye separation * 30.0 (known to
be a reasonable value)
