How about also adding a way to access the texture of the object? That 
way you could trace against the object, then use the object's texture 
normal(which was transformed along with the object) to perturb the real 
normal. The normal could be accessed by either a dot 
operator(preferable, something like this: Obj.texture.normal), or by a 
function(less flexible syntax, more keywords, etc. Something like 
get_tex_normal(Obj)).
