It IS!

Thanks, Josh.   That would have driven me crazy.
I'm not sure I would have ever found that, unless I resorted to blind "try
everything" mode.  I normally associate uv_mapping with some sort of object
instantiation, as in "use uv_mapping to apply whatever texture, instead of the
normal mode".  Instead, it looks like I'm having to use uv_mapping as the first
argument in the texture definition itself, before the pigment {} statement.

I honestly can't say that I've ever seen this before, or actually noticed this
for what it was.   Great catch.

Kenneth and Thomas - the object pattern does not use the intersection of 2
objects.  It partitions space between inside and outside of an object.  So I can
make a texture appear in the shape of an object, or everywhere _but_ where the
object is, or texture the object's 3D space in one way, and the space around it
in another.   Or layer that concept, as TdG and I have done in past scenes.

And you definitely are catching on to where I'm going with that.  ;)

(Note, the clipping of the torus is due to it being placed for proper
positioning in the 1st and 3rd triangles, so it gets clipped in the middle one.)
