    sna: Pass width/height to composite for rotated displays

    This is essential to handle displays that are too large to be rendered
    normally via the 3D pipeline and so that the bounds of the fixup region
    are known.

That will fix up SNA so that you can see the rotated screen, and you should be
able to drive glxgears at 60fps! Do bear in mind the 2048x2048 limit still
exists, and extra work is involved to circumvent that limit.

Hope this helps!
