Thank you for your comments.  However, I would like to evaluate a height
field at parse time, not render time.  I've been trying to use bitmap data
to add a deformation map feature to a mesh creation macro i've been working
on. I thought that the 3.5 function feature might be the way to go.  But i
can't figger it.  With MegaPov hf_height_at() i could loop through and
evaluate values at each point before rendering.  Thanks again.
