Unfortunately, this broke VLC, resulting in incorrect colours in videos.
The problem is that VDP_RGBA_FORMAT_R10G10B10A2 is passed to
vlVdpOutputSurfaceCreate. This can't work directly for presentation,
because the Present extension request PresentPixmap only works if the
pixmap depth matches the window depth, otherwise it returns a BadMatch
protocol error.

vlVdpOutputSurfaceCreate needs to check that the format passed in
matches the window (surface?) format, and fall back to the old method
otherwise.

If this takes significant effort, maybe just revert the commit for now.
