Algebra for generating a stream of events indicating when the canvas is ready to redraw. The algebra applies to a Renderer's Canvas data type instead of the F data type.
Return a stream that has an event every time the canvas is ready to redraw. The value is the approximate time in millisecond since a frame was last rendered.
