Should, I guess... doesn't.

I was just trying this out, having seen this thread about HF_Sphere macro,
and I get an error at the first array line in HF_Create, PArr [J][K], says:
vector expected but color expression found.

Nothing I try seems to solve the problem. I set it up in a scene file as
follows:

#declare Function=function {
 pigment {
  image_map {
   png "c:\images\test.png"
  }
 }
}

#declare UseUVheight=1;
#declare UseUVtexture=1;
#declare Res=<10,10>;
#declare Smooth=1;
#declare FileName=""
#declare Center=<0,0,0>;
#declare Radius=1;
#declare Depth=0.1;

#include "shapes.inc"

HF_Sphere
(Function,UseUVheight,UseUVtexture,Res,Smooth,FileName,Center,Radius,Depth)

Going by the Doc on this, I suppose I'm doing everything right.
