Thanks. One other problem is how to get the sipWrapperType pointer.... A sip 
generated extension module gets these pointers via api_export_module, but 
that is documented as a sip-private API. 

The non-obvious answer (but easy once you know it) is that these 
sipWrapperTypes are the same objects as stored in qt module python namespace.

Thanks again,

This is the inner loop of the rendering code for a custom graph widget. The 
optimisation target isnt the PyQt code itself, but rather the next layer up, 
which calls PyQt. It will be much more convenient for this C (or C++, or 
pyrex) code to call the Qt C++ API directly.
