    Add GdkRGBA struct to supersede GdkColor · 5a5f8081
    Carlos Garnacho authored
    GdkRGBA is a boxed struct similar to GdkColor, with the difference
    that it stores alpha information as well, and colors are stored in
    [0..1] doubles, in the cairo spirit.
    gdk_cairo_set_source_rgba() has been also added to allow easier handling
    of this new type.
