    tool-crop: Always express the "original" constraint as landscape
    
    All the other constraints, except square, are always expressed as
    landscapes regardless of the orientation of the original BaseItem.
    This inconsistency is exposed by portrait BaseItems, where the
    orientation changes from landscape to portrait depending on the chosen
    constraint.
    
    A subsequent commit will allow changing the orientation at will. Always
    expressing the "original" constraint as landscape will help with that.
    Cropping portraits was already painful, so this doesn't make it much
    worse.
