/* EelLabeledImage is a container widget.  It can only contain internal 
 * widgets.  These internal widgets are can be a EelLabel and/or a 
 * EelImage.  These internal widgets are created as needed.  That means
 * that EelLabeledImage can always be used for "free" instead of a 
 * EelLabel or EelImage.  The only overhead is that of the GtkObject
 * machinery.
 *
 * The position of the label with respect to the image is controlled by the
 * 'label_positon' attribute.
 *
 * By default the internal image and label widgets are sized to their natural
 * preferred geometry.  You can use the 'fill' attribute of LabeledImage
 * to have the internal widgets fill as much of the LabeledImage allocation
 * as is available.
 *
 * LabeledImage also has x_padding/y_padding and x_alignment/y_alignment 
 * attributes that behave exaclty as those in the GtkMisc class.
 *
 * Note that the alignments are ignored if the fill attribute is TRUE.
