Something which I do not see in the docs is an explanation about how to
properly use 'pattern' in a 'function'. You don't say whether or not it will
be grayscale. Or maybe I just totally missed it.

Oh, good point. The documentation kind of assumes you know that the pattern
functions are return a scalar, not a vector, and thus a pattern is
grayscale. Maybe the docs should explain the difference between pigment and
pattern functions better, in particular for the image-map-function ... Ingo,
are you reading this?

Could you add a scentence or two in the function-image-type section that
explains that a pattern function will be easier to use for a function-image
compared to a pigment function which generates an unnecessary color
information that is useless when the function-image is used for a
height_field.

And maybe try to make it a bit more clear that a pattern function returns a
scalar and a pigment function returns a color vector (I am not sure how and
where to add this though).

I'll figure out something.
