If a mask was started on an area that is now hidden by a crop, the mask marker is not visible anymore when entering mask mode (K).
Modifying a hidden mask means modifying the current crop to get access to the mask marker and setting the crop again after modification.
Masks markers out of crop should either:
- show on the outside edges of the picture area
- be allowed to be moved in the crop area if the mask is also active here
