So, this just popped into my head, inspired by your comment and my thinking
about Vrand_on_Bezier -

There are the clock / spline macros that plot points uniformly over a spline.
Scan in the data across the u direction, saving to a spline / array, and
increment down the hf in the v direction.

Then rather than plot the point on the hf directly, plot it on the spline.

If those macros work for bezier splines, then that may be a solution for Cousin
Ricky's scene as well.
