* clutter/glx/clutter-backend-glx.c:
	(clutter_backend_glx_get_features): Assert if we don't have a
	GL context here or if it's not matched to a drawable. Asserting
	might seem too drastic, but if we don't have a valid GL context
	here then Clutter will segfault anyway, and I'll take an assert()
	over a hard to read, deep in GLX guts backtrace any day (and
	twice on a monday).

	* clutter/x11/clutter-backend-x11.c:
	(clutter_backend_x11_get_features): No need for a variable here.
