Doesn't everyone?

I've never understood why we *can't* do this. A texture, whether it's 
patterned or not, is just a texture. You shoot a ray at an object and 
the texture contributes a few numbers to the color calculation for the 
ray. If it doesn't matter whether the top layer is patterned or not, and 
the texture engine can perform the necessary math to work out the color 
of a layered texture at a given point, why can't that non-top layer be 
patterned?

It almost sounds like some stupid oversight that no one felt 
particularly motivated to fix.. or else the code is old and crufty and 
makes assumptions about textures that aren't necessarily true today, but 
rewriting the code would take a lot of work.

(In which case, this had better be fixed in the semi-mythical 4.0 release.)
