    tool-crop: Create the surface after the correct zoom factor is known
    
    When revisiting a cropped item (ie. the item's pipeline already has
    gegl:crop in it), we remove the cropping constraints so that we can
    display the item in its entirety. Therefore, we should use the view's
    zoom after the constraints have been removed, not before. Otherwise,
    the zoom factor known to the tool won't match that of the view it is
    actually drawing on.
