Returns the graphics reset status as reported by GetGraphicsResetStatusARB defined in the ARB_robustness extension.

Note that Cogl doesn’t normally enable the ARB_robustness extension in which case this will only ever return

COGL_GRAPHICS_RESET_STATUS_NO_ERROR.

Applications must explicitly use a backend specific method to request that errors get reported such as X11’s cogl_xlib_renderer_request_reset_on_video_memory_purge().
