eval_pigment is a macro in the functions.inc file.

It is, as has been pointed out in the past, simply a wrapper for a pigment
function.


#macro eval_pigment(pigm, vec)
    #local fn = function { pigment { pigm } }
    #local result = (fn(vec.x, vec.y, vec.z));
    result
#end

You plug in your <x, y, z> vector, and out pops the <r, g, b> color vector at
that point in the pattern, image_map, etc.
