    Comment:    The various flags associated with each control point on the path. They
                are as follows :-
                IsSelected - TRUE if the control point is selected
                IsSmooth - TRUE if the control point should be smoothed when the path is
                edited
                IsRotate - TRUE if this bezier control point should be kept colinear with
                its partner
                NeedToRender - TRUE if we need to render this control point during an edit
                IsEndPoint - TRUE if this control point is an EndPoint
                Spare1-3 - No specific use as yet but can be used for any localised task
                you perform on a path
