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.
