0001649: SNL: colormap 'log' option
Feature request for having the colormap have a 'log' option. Meaning show me the 'log' of the value that I want to colormap (would affect both coloring and scalar bar values).
No tags attached.

Actually, this is not clear. The request is that the color map have a logarithmic option such that the color contours are spaced logarithmically. The actual values themselves are not changed to a log spacing, the contours are changed to a log spacing:

e.g.

for data which has a min/max of 1.0e-5 to 1.0

linear spacing: 0.0 0.25 0.5 0.75 1.0
log-spacing: 1.0e-5 1.0e-4 1.0e-3 1.0e-2 1.0e-1 1.0

NOT: -5, -4, -3, -2 ,-1, 0
