Color selector

[Cyrille Berger]

Hi,

We had a little discution on irc (involving Boudewijn, Casper and me) this 
afternoon on the color selector. The starting point is that the current trunk 
docker is a little bit big, and I am not sure that all of it (like CMYK combo 
box, or any combo box at all) is needed in the docker. But, clearly, a lot 
still need to be discussed.

* As Casper pointed it out, we should start by defining the purpose of a 
docked
colorchooser ? What's the goal ? And what's need ?

The main use case we saw for this docker is someone drawing, then selecting a 
color, then drawing, then selecting a color, then drawing, then...

* some other random thought that were raised during the discution:
 - Color selection should happen in percentage or double (that said color 
selection for HDR imaging is still an open discution)

About the dialog:
 - hsv in the big color dialog is a good thing
 - we cannot do without cmyk but it should be more related to the current CMYK 
color space if the current paint device is in a CMYK, not to some random 
default

About the docker(s): 
 - a smaller hsv-based color selector with history for the default docker 
(with a square, circle or triangle color area ?)
 - the big color selector can stay as a docker, but should not be the default 
one
 - and we need a third docker with a color selector dedicated to the current 
color space (especially for special case like YCbCr), with sliders for each 
of the components

So if you have opinion or thoughts on the subject, or use cases, we are all 
open to hear them !
