I won't be able to spend time on this short term --- it took me too

I hope that wasn't on account of wx. These were not show-stopper
issues.
Since we are not under pressure, I committed another set of changes
to Wx+WxAgg. Now they should only render the graph when the
window is shown. I would appreciate having windows and linux users
beat on it for a while, in particular testing lasso_demo before and after
printing.
I'm also attaching embedding_in_wx5.py, which puts a pair of graphs
into a wx notebook.
