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. Reviewed-by: Robert Bragg <robert.bragg@intel.com>
