the ranges definitely need a way for the user to hook in and provide
his own type of mapping. though log/sqrt are usefull mappings, the
range mapping facilities shouldn't be limited to this fixed set.
putting gtk_range_set_inverted() and maybe assorted friends is only
a shortterm kludge, use a user-configurable signal right away and
don't bloat the API ;)
