wxmpl provides a subclass of wxPanel, so it's there somewhere. I haven't 
done mouse events, so I I don't know where yet. I do think wxmpl could 
use some more work.

I'm guessing that what's happening is that the two mouse clicks close 
together are getting caught as a double-click, so the second one doesn't 
show up as a single click.

ugh. I'd poke around more in the wxmpl code. Maybe I'll do that myself.

OK-- I started doing that, but first I just tried binding a event to a 
wxmpl.PlotPanel, and it works fine. I've enclosed a little sample. It 
should write to the console when you left, right or double-left click on 
the PlotPanel.

Note that when you double click, you get one left click event and one 
double click event, but not two left click events.

Of course, you'll now need to figure out how to query the FigureCanvas 
to see what the axes coords are, but I'm sure you can find code on MPL 
that will give you hints.

By the way, you could hack backend_wx.py to add the double click events, 
but that would be ugly if it wasn't added everywhere else in MPL -- 
which is kind of why I think that way lies madness ;-)
