sna: Apply affine transformations to HW cursors

Until now we only applied pixel-exact rotations to the cursors. However, this left the cursors ignoring scaling and so appearing incorrect on outputs with transformations applied. An extra complications comes from making sure that the scaling routine is signal safe.
