    -- A @GdkPaintable@ that displays the contents of a widget.
    --
    -- @GtkWidgetPaintable@ will also take care of the widget not being in a
    -- state where it can be drawn (like when it isn\'t shown) and just draw
    -- nothing or where it does not have a size (like when it is hidden) and
    -- report no size in that case.
    --
    -- Of course, @GtkWidgetPaintable@ allows you to monitor widgets for size
    -- changes by emitting the [Paintable::invalidateSize]("GI.Gdk.Interfaces.Paintable#g:signal:invalidateSize") signal
    -- whenever the size of the widget changes as well as for visual changes by
    -- emitting the [Paintable::invalidateContents]("GI.Gdk.Interfaces.Paintable#g:signal:invalidateContents") signal whenever
    -- the widget changes.
    --
    -- You can use a @GtkWidgetPaintable@ everywhere a @GdkPaintable@ is allowed,
    -- including using it on a @GtkPicture@ (or one of its parents) that it was
    -- set on itself via 'GI.Gtk.Objects.Picture.pictureSetPaintable'. The paintable will take care
    -- of recursion when this happens. If you do this however, ensure that the
    -- [Picture:canShrink]("GI.Gtk.Objects.Picture#g:attr:canShrink") property is set to 'P.True' or you might
    -- end up with an infinitely growing widget.
