+These methods return the coordinates of ellipse vertices of
+major and minor axis. Additionally, an example gallery demo is added which
+shows how to add an arrow to an ellipse showing a clockwise or counter-clockwise
+rotation of the ellipse. To place the arrow exactly on the ellipse,
+the coordinates of the vertices are used.
