    Theming: Remove the GtkColors class
    
    GtkColors was providing a quick color lookup for various color types
    (foreground, background, text, dark, etc.) for all possible widget
    states.
    With the new theming infrastructure in GTK 3, colors can now depend on
    the style class: "background", "button", "entry", etc.
    So keeping a lookup cache for colors is not feasible anymore. Widgets
    should use the StyleContext API to figure out their colors.
