Ah, *now* I get it.  (Did I manage to overlook the documentation on 
this, or is it one of those moving targets?)

It's not obvious from the SIP files -- for example, in qcanvas.sip, it 
looks like it's defining a subclass converter just for stuff in QCanvas 
and below.  But in the generated file, it's clearly overlaying (? is 
there a better word to describe this?) the QObject converter from 
qobject.sip.

Yep... I now understand the grand vision of how it all works.  Thanks!
