Fine for me.

If you have any time, HSLModifier don't work properly with 16 bits image (i 
suspect a problem too with 8 bits image).

Can you take a look my comments in source code and give me your viewpoint ?

Thanks in advance

Nota : HSL tool is the last one from core plugin to port in 16 bits (:=)))...
