That would be cool. Probably won't happen until 4.0...  ;)

I think you could closely approximate anything you'd like by using an array and
filling in points by interpolating with the desired function.
Then use the array to define the color map.

It's a workaround, but for most things it probably gets you close enough.
Like most things, it could probably be written as a macro, to accept a
[partially filled] array containing a few defined points, the number of
subdivisions desired between 0 and 1, and the interpolation function.
