 Bezier

Class Bezier represents a Bezier second-order curve in parametric view, and is given by start, control and end points on the plane.
 Intersection If crossing exist, then result can be of array of points, or full or brownout coincidence of shapes.

If variable isCoincidence=false, it means that shapes are crossing and not equally.
 Line Class Line introdaction line at parametrical introduction, given by points on plane start and end and realized to support internal method lineTo().
At class realized properties and methods, they help you take access to basic geometry properties of line.
Points, belongs to line defines by time-iterator.
