Okay, I've hacked together a routine to convert arrays to QPolygonF in C++
to speed up this loop. It appears to work and is a lot faster than pure
python.
Unfortunately I've hacked in the support to get i

Just to add a quick benchmark shows filling a QPolygonF in Python with

So, I have implemented my PyQt4/veusz application, which can be seen here:

It looks good, but the speed is not usable for a real dataset. I've
got anti-aliasing turned off, which helps a lot, but it still needs a
