    <summary>
      Implemented by AtkObject subtypes on behalf of components which
       display image/pixmap information onscreen, and which provide
       information (other than just widget borders, etc.) via that
       image content.
    </summary>
    <remarks>
      <para>
        <see cref="T:Atk.Image" /> should be implemented by <see cref="T:Atk.Object" /> subtypes on behalf
        of components which display image/pixmap information onscreen,
        and which provide information (other than just widget borders,
        etc.) via that image content. For instance, icons, buttons
        with icons, toolbar elements, and image viewing panes
        typically should implement AtkImage.
      </para>
      <para>
        <see cref="T:Atk.Image" /> primarily provides two types of information:
        coordinate information (useful for screen review mode of
        screenreaders, and for use by onscreen magnifiers), and
        descriptive information. The descriptive information is
        provided for alternative, text-only presentation of the most
        significant information present in the image.
