[Urwid] Rendering and caching

[Aaron Gallagher]

How are rendered objects cached, and how does urwid know when to call  
the render function? I've tried making my own widgets, but they only  
seem to work if I call render functions from preexisting widgets;  
returning my own canvases renders once, but never calls render again.  
I would also like to know how can I force rerendering given an object?

And is there any way to make text markup easier? Using lists of  
markup lists is bothering me a bit.
