Original commit message from CVS:
2005-11-03  Julien MOUTTE  <julien@moutte.net>

* ext/directfb/Makefile.am: Prepare for liboil usage.
* ext/directfb/dfbvideosink.c: (gst_dfbvideosink_show_frame),
(gst_dfbvideosink_buffer_alloc):  Prepare for liboil, handle
rendering in external surface correctly. Will commit a neat
example soon.
