Returns the Parameter of the given point projected into the plane of this ellipse (pp). For a circle or arc this is the radian of the angle of the point. For an ellipse this is the value (a), where e.x = center.x+majorradius*cos(a), e.y = center.y+minorradius*cos(a) yields a point (e) on the ellipse so that (pp) coincides with the line (center,e).
