Original commit message from CVS:
* ext/swfdec/gstswfdec.c: (gst_swfdecbuffer_get_type),
(gst_swfdecbuffer_class_init), (gst_swfdecbuffer_finalize),
(gst_swfdec_buffer_from_swf), (gst_swfdec_render): Add a subclass
of GstBuffer that wraps SwfdecBuffers.  Fix a massive memleak
because the video buffers previously never got freed.
