[Paraview] Color Table File Format

[Burlen Loring]

great! I have just spent some time experimenting with 3.14 and it seems 
that the xml file format has not been updated to support the separation 
of color control points and opacity control points. That would be a huge 
improvement to support this in the xml format. by the way I also noticed 
an issue in the first set of luts and fixed it, new file is on the wiki.

They are huge help for making nice pseudo color plots, but they are cumbersome when volume rendering since opacity is tied to each of the 256 color points. changing the transfer function requires tweaking a large number of them and they are very dense in the UI so you can't even click on them individually. I recall in 3.14 the transfer function editor was improved, does pv now support a separate opacity and color point in the transfer function color map table? if so them was that also added to the xml format? If not this may be something to think about in the future.
