Well, that one should be able to use an onmouseup event in combination
with a check to the change. Like, you can set a temporary attribute
named, say, "oldwidth" onmousedown, and then you have an if(this.width
!= this.oldwidth){ foo; }, or something to that effect, included in
the onmouseup, which should behave properly. (From my vague
recollection of the earlier bits of this thread, I understand that
onmouseup isn't exactly operating as expected, or something to that
effect.)
If we start getting into combinations of things like onwidthchanged,
there would almost necessarily have to be an entirely new family of
events added, such as onheightchanged, onxchanged, onychanged, etc,
simply to do what a fully functional onmouseup plus a check to a
difference in the attribute would accomplish.
