> sna: Handle rotated slaved scanouts
>
> As per the usual handling of rotated scanouts with unsupported
> rotations, we stage the drawing onto a backbuffer then rotate onto the
> crtc later. The difference here is that we must read the contents from
> the master pixmap rather than our own screen pixmap.

> Spotted was looking at slaved scanouts mistakenly setting the CRTC
> transformed flag.
