Thanks Bill!   :)

I don't understand what the pointy curves are - shouldn't they all have rounded
minima?

I'm happy that some of these basic curve shapes that are often used in modeling
are being implemented into the source of your fork.


Also for your consideration, it would be useful to have f_bezier or f_bernstein
for modeling quadratic or cubic curves, and perhaps f_voronoi which would take a
list of seed values as an argument.
