In fact, wxPython can resize icons, within reason given their base  
resolution, on the fly. I originally had the 'classic' icons resized  
because of a bug in earlier versions of wxPython. That has been  
dropped but looks like it could easily be reimplemented.

I think I spotted where this is this morning but don't have time right  
now to look at it in detail.

This may not work with aui toolbars. These are somewhat special. But  
will look into it.
