I have run the complete gnuplot unit-test suite
against it. ;-)
I have taken some sample data set and tried
the new algorithms out on them and visually
inspected the results. The "gnu-valley" mini
data set from the gnuplot documentation is

Yes. Both of these are features that dgrid3d itself provides,
and which I have not modified. I merely have added some
additional smoothing kernels (and syntax and options to

I don't think this is really necessary. The Gaussian
kernel is probably the most general, all-purpose
kernel in this patch. I don't want to patronize the
reader, but we can include a sentence like "Unless
you have special needs, the Gaussian kernel is
likely to give satisfactory results."

I can provide some demos for inclusion into the demo/
folder. I think that is a good idea.
