Very very nice!

I always wondered why POV-Ray does not interpolate the image for height fields,
as it can for image_maps. It is one of the reasons I wrote my curves.inc. The
idea to use it to interpolate images with different splines to vary the HF
output. Imagine using a TCB spline and vary the tension of the curvature.

But then I got side tracked by doing the curves.nim version and povmesh.nim to
speed things up a lot, but never got to create any proper HF mesh with it.

(the Nim version has better explanation of what the various parameters do than
the inc file)
