That's after you register a "hit".  But can you actually register a 
"hit" when the mouse is within n pixels of the xlet?

I ran into this with the svg-data structures stuff.  I made some points 
on a graph grow when the mouse enters them.  But it turns out it's much 
more usable if you have an insible area larger than the point to 
register an "enter" event and then grow the point to that size.
