I guess this is just one of the prices for using functions absolutely everywhere
in the program. The x/y orientation works great for a pigment, but for a height
field,the need fr an additional transform is not intuitive. I had the same
problem using trace with a function-generated h/f. I had assumed it was a bug.
Thanks for the info.
