I guess this is why they call CVS bleeding edge, eh? Yes, bug crept
in last night and is fixed in CVS as of early this morning. Note to
self: don't do commits over an xterm past 11PM.
However, the wx backend has not yet caught up with the latest changes
since Jeremy is out of town until Friday. I expect he'll do an update
then.
I've uploaded a Nov 15th snapshot which has a working wx backend to a
temporary web site. There are still a number of known bugs (eg,
figure placement and size) that Jeremy is systematically squashing but
it won't be long (target date early December). Have fun testing.
Please let us know if you find any bugs not in the known bugs section
of backends/backend_wx.py.

This is the way VTK does it and it is great. All three mouse buttons
are used for pan, zoom and rotate. The only problem is for
application developers using matplotlib, who will probably want to
reserve some of the mouse buttons over figures for context menus or
measurement tools, etc... I have done both in my applications. Its
possible to do both via different toolbars, but there are only so many
hours in the day. I'll let it simmer.

Hi John,
New navbar sounds good, esp. replacing arrows with hand. Default to hand
mode (maybe even revert after completing an operation with other modes).
I'm not so happy with all the modifier keys.
I'd have one modifier key, Shift, that constrains the motion, and
everything be drag-based:
	* In pan mode, Shift drag restricts motion to whichever the
	 principle mouse direction is. I can keep it within 45 degrees
	 myself, and this allows me to easily change x, then y.
	* In zoom mode, Shift drag zooms along principle mouse
	 direction. Otherwise zooms as radial distance of drag.
	 Mousewheel zoom zooms both axes.
	* Zoom rectangle: Shift-drag maintains axis ratio in
	 drawing the rectangle.
I might even suggest replacing the "pan" and "zoom" buttons by just using
left-click and right-click for the drag. That way I can change tasks
without mousing around. Zoom-rectangle could even be middle-click.
