Hmmm... I thought I added that first (to pcb).

Eagle does the same as PCB though.  Same direction, too.  Google maps
zooms the same way.  I think we got it right.

In fact, I keep trying to use the middle button to zoom/pan in other
applications now, and get frustrated when it doesn't just work :-P
