The stereoscopic projection mode used for the left and right eye scenes.

Member	Value	Description
eStkGraphicsStereoProjectionParallel	0	Parallel projection. Parallel projection will ignore any projection distance that has been set and instead use a parallel projection for each eye. In parallel mode all objects will appear to go into the screen. Head mounted stereographic systems typically require a parallel projection.
eStkGraphicsStereoProjectionFixedDistance	1	Fixed distance projection. Objects at the fixed distance will appear to have no depth. Objects further than the distance will appear to go into the screen. Objects nearer than the distance will appear to pop out of the screen.
eStkGraphicsStereoProjectionAutomatic	2	Automatic distance projection. Automatic distance projection will ignore any projection distance that has been set and instead automatically calculates the projection distance based on the distance between the camera and the center of the scene.
