It does.

Err, this is good idea.  I'll put it in.

I'm guessing that using inside_region() as the first filter will  
lessen the computational burden for text.  To even perform the  
operation on text, the user must click within the rectangular bounds.   
To perform the operation on multiple text objects, they must overlap  
and the user must click in the overlapping rectangle.  With the  
inside_region() as the first filter, I'm inclined to leave the  
shortest distance for text as is...
