Comment (by jdemeyer):
Replying to [comment:50 ppurka]:
> So, every time the ranges of `x` and `y` do not form a square, there
will be `nan`s in the matrix `vals`, and this can not be avoided if you
want an accurate plot. So, it is pointless to try and remove `nan`s.
I completely disagree with this. At the end, you're drawing an arbitrary
3D figure given by faces and vertices. This doesn't have to lie over a
square grid. Of course, currently the functions are written to require a
square grid, but there is no fundamental reason for this. I agree it's not
trivial to change this, but don't blame Solaris.
