My original message was this:

============================================================================
In [1]: gcf().set_figsize_inches((8,8),forward=True)
---------------------------------------------------------------------------

      267             canvash = h*dpival

A quick look at the backends code shows this:

      def resize(self, event):
          width, height = event.width, event.height
          self.toolbar.configure(width=width) # , height=height)

So quite obviously, this doesn't work: it's expecting an event object, and a
pair of numbers is being passed.

I'm not sure what the proper fix should be here, I don't really know the code
flow well enough.

I should also note that the gcf().set_figsize_inches((8,8),forward=True) seems
to produce a different on-screen result per backend (in some it doesn't do
anything, in Qt it stretches the figure only horizontally, ...)  That code
seems to be pretty much broken.

I noticed that figure(figsize=(8,8)) seems to work fine, but I'm not sure how
to programmatically resize an existing figure, given the above problems.
============================================================================

Beyond this, I'll leave it to the backend experts as to what the right choices 
should be.  I just noted that shipping a feature _known_ to break on all but 
one backend doesn't sound like the best approach :)
