I could implement bits() (and scanLine(), jumpTable() and colorTable()) to 
return void*. You then have the choice of passing the Python object to your 
extension and calling sipConvertToVoidPtr() to extract the address, or using 
the Python int() on the object to convert it to an integer before passing to 
your extension.
