* sys/xvimage/xvimagesink.c: (gst_xvimagesink_xwindow_decorate),
(gst_xvimagesink_xwindow_new),
(gst_xvimagesink_update_colorbalance),
(gst_xvimagesink_handle_xevents), (gst_xvimagesink_xcontext_get):

Fix handling of some of the X atoms. If the last parameter is True,
XInternAtom won't create the atom if it doesn't exist, and therefore
might return None. This causes X errors on Xv implementations that
don't provide the colour balance attributes.
