Comment (by glynn):

 Replying to [comment:3 glynn]:

 > Ultimately, decent histogram equalisation for FP data will require
 replacing the use of the Cell_stats code with something else (i.e. binning
 the data into arbitrary FP ranges, rather than one bin per integer
 category). Also, it will need to use logarithmic (geometrically-spaced)
 bins in order to work well with -g (log scaling).

 Implemented in r33889 (7.0).

 Currently hardcoded to 1000 bins, which should provide reasonable quality
 without creating excessively large colour tables.
