    <summary>
      A GtkIconSource contains a <see cref="T:Gdk.Pixbuf" /> (or image
      filename) that serves as the base image for one or more of the
      icons in a <see cref="T:Gtk.IconSet" />, along with a
      specification for which icons in the icon set will be based on
      that pixbuf or image file. An icon set contains a set of icons
      that represent the same logical concept in different states,
      different global text directions, and different sizes.
    </summary>
    <remarks>
      <para>
      A <see cref="T:Gtk.IconSource" /> contains a <see cref="T:Gdk.Pixbuf" /> (or image
      filename) that serves as the base image for one or more of the
      icons in a <see cref="T:Gtk.IconSet" />, along with a
      specification for which icons in the icon set will be based on
      that pixbuf or image file. An icon set contains a set of icons
      that represent the same logical concept in different states,
      different global text directions, and different sizes.
      </para>
      <para>
        So for example a web browser's "Back to Previous Page" icon
        might point in a different direction in Hebrew and in English;
        it might look different when insensitive; and it might change
        size depending on toolbar mode (small/large icons). So a
        single icon set would contain all those variants of the
        icon. <see cref="T:Gtk.IconSet" /> contains a list of <see cref="T:Gtk.IconSource" /> from which
        it can derive specific icon variants in the set.
      </para>
      <para>
        In the simplest case, <see cref="T:Gtk.IconSet" /> contains
        one source pixbuf from which it derives all variants. The
        <see cref="C:Gtk.IconSet(Gdk.Pixbuf)" /> constructor handles
        this case; if you only have one source pixbuf, just use that
        function.
      </para>
      <para>
        If you want to use a different base pixbuf for different icon
        variants, you create multiple icon sources, mark which
        variants they'll be used to create, and add them to the icon
        set with <see cref="M:Gtk.IconSet.AddSource(Gtk.IconSource)" />.
      </para>
      <para>
        By default, the icon source has all parameters
        wildcarded. That is, the icon source will be used as the base
        icon for any desired text direction, widget state, or icon
        size.
