Proposed Submission: Figure Layout Management

There have been some additional memory leak fixes since 0.54.2. Glad
we could keep you on board!

Ahh, just the kind of developer we need....

I really liked your demo. So much that I think we should include it
into the distribution and incorporate versions of your widgets for
each backend. I think we should have a button on the standard toolbar
that launches your dialog box. I can do the one for GTK - perhaps you
or Todd would like to incorporate your changes into backend_tkagg so
that a toolbar button launches the dialog box you wrote.

It would also be nice to add checkboxes for turning off y tick labels
for all but the first column and turning off x tick labels for all but
the last row.

Any takers for doing the wx version?

Another question: what would happen if your code were run on non
subplot axes, eg with those examples/axes_demo.py?

A word of warning: in your demo code, you define a function set.
There is a matplotlib.matlab function with the same name...

Oh, and if the user wants to shift individual subplots
