    annotation: Make annotation title independent of theme
    
    The note text (sticky notes) annotation uses a custom background
    color (yellow by default). Having the title adjustable to theme,
    breaks dark-themes, because the title becomes white on yellow
    background.
    
    We set a fixed black and grey as the foreground colors for the
    title, which works on yellow background.
    
    Fixes #664
