Supported output target back-buffer options.

If the final output target is an on-screen OpenGL context which supports active stereo rendering then it is possible to send the output to either the left or right back-buffer.

If the final output target is an offscreen target or if the on-screen OpenGL context being used does not support active stereo, then only the 'center' option can be used. 'Center' is the default back-buffer associated with an OpenGL context. If 'left' or 'right' options are specified they will be ignored in these cases.

This option is currently ignored if the active rendering API is not OpenGL.
