+ * \brief Scalar Widget - A labelled text box, with spin buttons and optional
+ * icon or suffix, for entering arbitrary number values. It adds an extra
+ * number called "startseed", that is not UI edittable, but should be put in SVG.
+ * This does NOT generate a random number, but provides merely the saving of
+ * the startseed value.
