Well, I spent one afternoon playing with cairo, trying to implement the triangle interpolation and the result was slower than matplotlib. So gave up and I'll just use what can be done with mpl currently. As to mayavi, I'd rather make it easier to install. The only tough dependency is VTK, that takes lots of time to build, we already got rid of all the others, so that's good.
