Disregard the previous patch, it was the wrong way to do it.  See
instead the attached patch, which takes the more correct approach of
blacking the xvimage at allocation.  (At least, YV12 images will be
blacked; YUY2 images will be the same as before.)

There is a bug however with vo_x11 when vf_expand expands horizontally,
because vo_x11's draw_slice ignores the x offset.  But who uses vo_x11
anyway. :)

The expand osd stuff still needs to be fixed though, but at least the
attach patch addresses our more immediate concern.

Thanks,
Jason.
