 To use this feature, bring up the Color Map Editor (View -> Color Map Editor). To the right of the color map display area, enable the advanced mode by clicking the gear button. Two editing tables will appear below, one listing color map data and color values and one listing opacity map data and opacity values.

The color table has four columns:
Value - the scalar value in the data set (range: scalar field range)
R - the red color component (range: [0, 1.0])
G - the green color component (range: [0, 1.0])
B - the blue color component (range: [0, 1.0])

The opacity table has two columns:
Value - the scalar value in the data set (range: scalar field range)
Opacity - opacity value (range: 0-1.0)

The first and last scalar values in the table are not editable because these values are set with the "Rescale to data range" and "Rescale to custom range" tools. Scalar values between the first and last scalar values are editable, however. Additionally, all color components and opacities are editable.

In addition, one can paste a whitespace-delimited color map table from text into the color map table widget (same for the opacity map).

 Oh my, that is just sweet! Very, very good job - both to Utkarsh for the requirement and to Cory for implementation. Wow!

Tested remote server, Linux, master.
