We could cook up a pause handler pretty easily.  This would let you 
develop controls that respond to mouse pauses.  The reason to use a 
handler for this is so that it can be used in multiple controls - or can 
be used to set the behavior of a control that might respond to clicks by 
default.  For example, an Information control (requests GetFeatureInfo 
by default) might use a click handler by default (responding to single 
or double-clicks) - giving this control a pause handler instead of a 
click handler would change it's behavior to respond to mouse pauses 
instead of mouse clicks.  No code floating around yet for this, but it 
shouldn't be hard to write.

A ticket would be the first step.  Then a patch.
