Comment (by wenzeslaus):

 Replying to [comment:23 vincent]:
 > {{{r.colors.matplotlib}}} does not provide exact percent values (did I
 miss something?).

 Well, it provides exactly the values which are on the input only converted
 to percents. If you provide it with 256 steps, it will give you that. To
 have all whole percents from 0 to 100, you would need to give it 101
 values (speaking about the current (and simple) implementation of the file
 input). In other words, it does not produce files which are nice to look
 at by human but the library function does not care. It is worth noting
 that both 101 and 256 colors (steps) are arbitrary choices and I don't
 know how to determine sufficient number of steps for a color table.
