Hey ppl, I've been having problems declaring pattern functions.  I don't
think it is possible...

Here's what I want to do:

#declare FOO = function 300,300 { pattern { agate} }

height_field {
  FOO(x,y,z)
}

It errors saying that it expects something other than a constant at the
first 300.

Any ideas ppl?

Here's what POV wants:

#declare HF = function{ pigment{A_Pigment}}
#declare HF_Detail=300;

 height_field{
  function HF_Detail,HF_Detail{HF(x,y,z).x}
 blabla
}

That's because you are using the function *image* syntax instead of a 
function. Only use the resolution when you are defining an image. You 
can't declare an image, so this fails.
