In the screenshot you sent, I noticed that the "Color Map" parameter was not
exposed by KDENLIVE. With the XML file, does KDENLIVE allow you to change the
color map? Any suggestions on other color maps that should be added or what
should be default?

The channel chooser and formula selection shouldn't be too hard to add. The
legend might be a little tricky. Frei0r doesn't provide a good way to render
text. So I would have to add a dependency on some other library like pango or
Qt.
I'll see if I can have a look at adding those things next week.
