ORIGIN_UPPER_LEFT is the default convention, and is supported by all mesa drivers, hence it seems reasonable to always report the caps to be enabled. On gles ORIGIN_LOWER_LEFT is generally not supported, so we rely on the caps reported by the host that depend on whether we run on an GL or an EGL host. For PIXEL_CENTER it is completely host driver dependend on what is supported, and since we do not report the actual host driver capabilities it is best to mark both as supported, this is how it works for a GL host too.
