At the moment, I'm still puzzled about how to get from the mouse position
to the aspect ratio position.  It's easy when you are moving the lower
right handle, but much trickier with the other handles.  It seems to me
that it's reasonable to have Ctrl+(move element handle) be fixed aspect
resize (though shift might be a better choice).  I can see few cases where
you really need to have horizontal/vertical movement for resizing
elements.  The same problems would apply whether we use a key modifier or a
menu entry.
