/**
 * SECTION: xfce-panel-image
 * @title: XfcePanelImage
 * @short_description: Scalable image suitable for panel plugins
 * @include: libxfce4panel/libxfce4panel.h
 *
 * > #XfcePanelImage has been deprecated since 4.18.1. It was mainly useful with
 * > GTK 2, and is not really adapted to GTK 3. Use #GtkImage instead, and
 * > xfce_panel_set_image_from_source().
 *
 * The #XfcePanelImage is a widgets suitable for for example panel
 * buttons where the developer does not exacly know the size of the
 * image (due to theming and user setting).
 *
 * The #XfcePanelImage widget automatically scales to the allocated
 * size of the widget. Because of that nature it never requests a size,
 * so this will only work if you pack the image in another widget
 * that will expand it.
 * If you want to force an image size you can use xfce_panel_image_set_size()
 * to set a pixel size, in that case the widget will request an fixed size
 * which makes it usefull for usage in dialogs.
