    -- GtkGradient is a boxed type that represents a gradient.
    -- It is the result of parsing a
    -- [gradient expression][gtkcssprovider-gradients].
    -- To obtain the gradient represented by a GtkGradient, it has to
    -- be resolved with 'GI.Gtk.Structs.Gradient.gradientResolve', which replaces all
    -- symbolic color references by the colors they refer to (in a given
    -- context) and constructs a t'GI.Cairo.Structs.Pattern.Pattern' value.
    --
    -- It is not normally necessary to deal directly with @/GtkGradients/@,
    -- since they are mostly used behind the scenes by t'GI.Gtk.Objects.StyleContext.StyleContext' and
    -- t'GI.Gtk.Objects.CssProvider.CssProvider'.
    --
    -- t'GI.Gtk.Structs.Gradient.Gradient' is deprecated. It was used internally by GTK’s CSS engine
    -- to represent gradients. As its handling is not conforming to modern
    -- web standards, it is not used anymore. If you want to use gradients in
    -- your own code, please use Cairo directly.
