[Bf-taskforce25] colour picker feedback

[Matt Ebb]

Hi,

We've had a few chats in IRC about the new colour picker, I thought  
I'd post an amended proposal here.

The new picker is very cool, but it has some drawbacks.

Good stuff:
* It's pretty
* It's nice and compact
* It's fast to use for situations that don't need high precision, like  
the persistent colour picker for painting tools

Bad stuff:
* We definitely need access to the R/G/B values and sampler directly.  
Hiding this behind a modifier key goes against the transparency that  
we're trying to achieve with 2.5
* It gets very annoying that the colour picker disappears after the  
first click (or drag). This means that you have to pull up the colour  
picker twice to set the colour properly (hue/sat/value). Hidden  
modifier keys don't count here.

So here's a proposal that hopefully combines the best of all worlds.  
The idea is that you can get the quick-tweak-picker with its hidden  
functionality as a shortcut, by dragging on the picker. This is  
available for people who know about it, but it's not the primary means  
of choosing a colour.

But by default, the way that most people will use the colour picker  
(with a click), it shows the relevant sliders and sampler.

cheers,

Matt
