  I'd still like to know how to see this.  That's why the assert() is there.  
I haven't found a way to trigger it yet, though I'm imagining that 
hypothetically one could have >n plots in a column in a window n pixels high.  
That would make at least one plot be 0 pixels high.  I think we should guard 
against that instead.  It's an absurd use case, and having a possibility of a 
null buffer/pixmap seems worse (ugly) to me.  The whole (relevant) idea 
behind the view objects design in the first place was that this case 
could/should not happen.
