Color picker idea

[Ben Frantzdale <frantzdb admin arhs net>]

I'd think it'd be nice if there were an option in the Gnome color picker
that worked like the eye-dropperin GIMP or PhotoShop. You could cick a
"select color from the screen" and then click anywhere to send that
pixel's color to the color picker. It'd be usefull if you are trying to
have some gnome colors match some non gnome (ie E) colors.
