The figure is currently drawn -> the point will be appended at the end of the figure * 2. A point is inserted at a userdefined position after the initial placement of the figure is finished * * In the second case we need to determine the proper insertion index. In the first case the index always has * to be -1 so that the point is appended to the end. * * These changes are neccessary because of a mac os x specific issue: If a users draws a PlanarPolygon then the * next point to be added moves according to the mouse position. If then the user left clicks in order to add * a point one would assume the last move position is identical to the left click position. This is actually the * case for windows and linux but somehow NOT for mac. Because of the insertion logic of a new point in the * PlanarFigure then for mac the wrong current selected point is determined. * * With this check here this problem can be avoided.
