Currently, the LAB option only refers to the lightness adjustment
(interpolation for lightness is done in the lab space if checked).
User interaction and interpolation for everything else goes through
the HSL model.

The code is a little strange here, things are done in RGB, LAB,
YUV and HSL in one short stretch of code. I'm still trying to
work out an optimization.

It might be nice (later) to have additional options for user
interaction in perceptually uniform spaces (full LAB support)

My original hack was for 16 bit support.  My current code is aiming at
U8,U16 and 32 bit float.  I can do this quickly through some simple
changes to the existing code, but I am not convinced that what
is there is correct and optimal.

Again I'll have to look at these.
