Remarks
The ICanvasRenderingContext2D::strokeRect method creates a path that requires the use of the ICanvasRenderingContext2D::stroke method to render the rectangle. The outline uses the current ICanvasRenderingContext2D::strokeStyle, ICanvasRenderingContext2D::lineWidth, ICanvasRenderingContext2D::lineJoin, and, when appropriate, ICanvasRenderingContext2D::miterLimit properties. If the w or h parameter is zero, a line is drawn. If the w and h parameters are zero, the rectangle is not drawn.
