Alan,
I've had a quick test, and I confirm your results. I have also taken a
look at the code and from what I can understand there seems to be no
effort to apply any transformation to the clip region. Looking at the
other drivers (including cairo) this seems wrong. Unfortunately all the
drivers do these things in different ways so it is hard to tell exactly
what the qt driver _should_ do. I'll try to delve further, but this make
take some effort. Note to anyone else investigating, this clipping code is
in bindings/qt/plqt.cpp NOT in drivers/qt.cpp.
