Original commit message from CVS:
2005-07-13  Andy Wingo  <wingo@pobox.com>

* sys/xvimage/xvimagesink.c (gst_xvimage_buffer_destroy)
(gst_xvimagesink_xvimage_new): Ref the xvimagesink while the
buffer points to it.
(gst_xvimagesink_check_xshm_calls): Don't use our xvimage buffer,
rather just doing X calls ourselves. Also fixes a memleak.
