Um, a normal *can* take a normal_map. A pigment can take a pigment_map, 
and a texture can take a texture_map. No finish_map, though...
And their syntaxes are all consistent...a normal_map takes normal stuff, 
a pigment_map takes pigment stuff, and a texture_map takes texture stuff.
The slope_map is just more like a color_map than a pigment_map, it 
interpolates between slopes, not normals, like the color_map 
interpolates between colors instead of pigments.
