There is no good reason beyond the fact that the dat is rescaled to
byte when it is read in. (memory wasn't cheap when Display was
written).

By adding it you would have to re-read the entire volume each time you
pressed the button. (with a new range).  Perhaps a better solution
would be to hack Display to read in data as double/float and then the
colourmapping would be a lot easier.
