+ *
+ * Widget which creates a #GtkPixmap from XPM data.
+ *
+ * Use this widget instead of #GtkPixmap if you don't want to worry
+ * about the parent container's "realized" state.
+ *
+ * Note that the drawback of the easy interface is that the actual
+ * #GdkPixmap and it's mask have to be constructed every time you call
+ * gimp_pixmap_new() and cannot be cached in memory without doing bad
+ * hacks.
