// Function: draw a line created by PEN.
// (in this case using create Pen. The advantage is that, when an object (pen) goes out of scope, using the structure will automatically call Dispose (), will be deleted PEN.
// If the object creation by other means (usually very fee resources), be sure to explicitly call Dispose (), such as:
// "Graphics G = this.CreateGraphics ();
// ........
// ........
// g.Dispose (); "
// IMPORTANT:
// create Pen, Pen color and thickness to obtain height of the client area and the Width
