Owen W. Taylor d16df5a5aa Add support for setting up stereo CoglOnscreens
If we want to show quad-buffer stereo with Cogl, we need to pick an
appropriate fbconfig for creating the CoglOnscreen objects. Add
cogl_onscreen_template_set_stereo_enabled() to indicate whether
stereo support is needed.

Add cogl_framebuffer_get_stereo_mode() to see if a framebuffer was
created with stereo support.

Add cogl_framebuffer_get_stereo_mode() to pick whether to draw to
the left, right, or both buffers.
