com.lightcrafts.model.CropBounds
A CropBounds is an immutable rectangular shape which may be at an arbitrary angle. It's used in Engine.setCropBounds(). It is always interpreted in the original image coordinates.
A special case is a CropBounds that defines an angle without a rectangle. Such a CropBounds indicates to the Engine that the image should be rotated, without specifying how the image bounds should update.

    // When crop mode starts, or when the user asks to reset the current crop,
    // use these CropBounds.  They are angle-only bounds, set to the nearest
    // multiple of 90 degrees.
    private CropBounds getUncroppedBounds() {
        if (bounds == null) {
            return new CropBounds();
        }
        double angle = bounds.getAngle();
        angle = (Math.PI / 2) * Math.round(angle / (Math.PI / 2));
        return new CropBounds(angle);
    }
