Original commit message from CVS:
* sys/directdraw/gstdirectdrawsink.c
(gst_directdraw_sink_buffer_alloc):
Make it so that gst_directdraw_sink_buffer_alloc uses the right
width/height.
Especially when looking through the pool of buffers, make sure that
the width/height of caps is used instead of the already negotiated
dimensions.
For example if a buffer with different caps is requested, i.e.
higher resolution, the caller would get a buffer with the old
dimensions and thus corrupt the heap.
