+	* graphics.cc (axes::properties::update_xlabel_position,
+	axes::properties::update_ylabel_position,
+	axes::properties::update_zlabel_position,
+	axes::properties::update_title_position): Use get_transform only
+	when it is required.
+	(text::properties::request_autopos): Remove redundant temporary
+	settting of autopos_tag to none.
