Improve color table creation controls

[markcmiller86]

Is your feature request related to a problem?

No user has requested this but I did encounter the need for it it using our color table interface to design a table meeting the goals of numerically controlled coloring

One aspect of color table creation is specifying the position within the [0,1] interval of each color.

• It would be nice to be able to specify position by typing actual numbers in instead of just by dragging the GUI widgets.
• It would be nice if the GUI widgets displayed the numerical value associated with them while they are being dragged (and maybe above they GUI widgets).
• It would be nice to use any database variable's [min,max] range (or manually entered min/max) instead of always [0,1] to specify/manipulate the color positions. This could be achieved by always storing positions in [0,1] internally but using whatever current min/max settings the user selected for the display of the positions during manipulation in the GUI or, storing min/max values along with positions as part of the color table.

Note, all of the above is currently achievable, inconveniently, with calculator and editing of xml files or by writing some python code that does same ops on a color control point list object. So, this just represents an improvement in the GUI.

Here is where we explain how to do this in python, as you mentioned.
