Kinda; it searches down the focus trace until it his the bottom, and then 
walks down the sprite trace if the two are the same at that point.  The 
point is that our redirection should follow the same path.

heh.  From inside the X server, it's more like events are sent *to* 
devices (where the 'device' is the X server abstraction, not the physical 
entity).  In any case, events delivered while a device is grabbed should 
still be subject to redirection.

yes.

Yes.  Any pointer motion should generate appropriate crossing events.
