Just a little note for poeple as me who use almost every 3 strokes the 
color picker ( Control key while painting , mapped on my stylus button ).
It's happen to me to do small unwanted gesture while Control is pressed 
and painting ; it can be micro lenght stroke at the moment of color 
picking of 3 or 4 pixels. But it would be a disaster if Krita understand 
to sample color of 4 pixel radius at this moment and set it.

So, I like the idea ; I just prevent that the feature should try to 
'guess' intentionnal action of user to define a radius.
And not record the pointing of stylus who never does 'clean' button 
click ; but always add a little strokes in it.

My two cents :)
