method?

They are image maps applied to the patches using uv mapping.  I had to
change a few things from uvpov to get it to work correctly.  It's pretty
much the same as uv mapping in MegaPOV but I replaced the two uv vectors
with four, allowing one to specify the four corners of a quadrilateral.
Just got this incorporated with the sources for MegaPOV today, so I'll
be tinkering with the photons.  :)
