I agree completely.  And this seems like an ideal thing for a 
user to code up and submit. [grin]  After I get to a stopping
point on my current (late) project, and after I write the 
zoomraster howto, maybe I'll do it.

It would be nice to have a whole suite of mapping functions
to map one scale to another.  For instance, it might be nice
to have a kind of Transform superclass under which we might 
have boilerplate subclasses that, say, map a linear scale
to a log scale, or any other uni-dimensional warping function.
(This strikes me as a generalization that would include EZBin
as well.)  Then we can lump together uni-dimensional mappings
to create higher dimensional mappings.  We could use these to
do things like optimizing models by using higher resolution in
interesting parts of, say, a space or data structure, and lower
resolution in the more uninteresting parts.  (Note that I said
optimizing *models*, not execution. [grin])
