Remarks
When you create a CanvasRenderingContext2D object, it has a transformation matrix that identifies the current state. The ICanvasRenderingContext2D::scale method modifies the transformation by multiplying the matrix by the specified factor. For example, context.scale(1,.5) halves the vertical (or y-axis) values that are used in context and leaves the horizontal (or x-axis) values the same. Similarly, context.scale(2,2) doubles the size of the graphics.
