Neil Roberts e7b50a6cba renderer: Only check certain constraints when selecting a driver
Only COGL_RENDERER_CONSTRAINT_SUPPORTS_COGL_GLES2 affects the driver
selection and all of the the other constraints are only relevant to
the winsys selection. However Cogl was trying to apply all of the
constraints to the driver selection which meant that if any other
constraint was specified then it would always fail. This patch makes
the driver selection filter out all other constraints based on a mask
defined in cogl-renderer-private.h.
