Yes, although a version calculating the dot product with another vector
could also be interesting.

Probably not, although memory use will also be slightly higher, because it
needs a TPATTERN structure.

A pattern giving the slope of an object just like the slope pattern right
now, but that can be applied to any other object too.  The value would be
constant in direction of the slope vector.  Don't know if that would be of
much practical use, but you could for example have a CSG of a heightfield
and some objects with a slope texture of the plain heightfield.  It would
also be possible to use 'eval_pattern' on this.
