The problem is, there are no more Open Source developers interested in Xara Xtreme.

The graphics engine of Inkscape is really slow. That's the reason why the Inkscape developers are trying to change the code to use another graphics engine. But it's a long way to go. The code is in development (since months).

I don't think, that's possible to use Gimp's graphics engine.

Once again, the question is why should a developer spend time and effort on it?
