+	Added option to use the center of a bounding box as the drawing reference.
+	Added ability to set line stroke width.
+	Added option to add a perpendicular line.

+	Added "Draw all labels" checkbox.
+	Added option to flip the label orientation.
+	Added support for "Draw every x lines" = 0 in order to remove lines.
