    motion controller: add details to signals
    
    The ::enter and ::leave signals get emitted up and down the
    connecting path between the old an the new pointer location.
    
    The signals are less useful if you can't find out where along
    the path you are. That is what crossing mode and detail are
    about, so add those to the signals.
