Cool.

a rubber band zoom has not been done yet, I would love to have one. 
However, for ka-Map I think it is important to implement a rubber band 
zoom that is sensitive to both the aspect ratio of the current view AND 
the available scales.  This means that the box should be drawn in the 
same ratio of width to height and it should be drawn in sizes that match 
what the user will seem when they actually zoom.  This means that the 
box will 'snap' between various pre-set sizes as the user moves the mouse.

I'm not opposed to a different type of rubber band zoom, but I think 
this one is the most visually accurate for the user and is the one I am 
most likely to want to add :)  If you implement it differently and want 
to contribute it, I'd like to hear arguments for/against my proposal 
from the others on the list

Cheers

Paul
