SF: Change rounding behavior in setGeometry

- Add an option for a transform to round outwards instead of to the
  nearest pixel.
- Use this new rounding behavior when converting the crop rectangle
  from display-space to layer-space. Otherwise a pixel that will
  partially be on the screen might be marked as transparent.
