Thanks, those looks accurate, but ... - did you notice that item 5.3
is missing? That is the part I am most wondering about, the constants.
However I think I got the needed information from a GIMP developer.

But it is a bit tedious to implement. Are there any good descriptions
of vector/matrix handling in elisp? Like everyone else I am fond of
reinventing the wheel, but not every time.
