MouseMove

doodle.interact.algebra.MouseMove
trait MouseMove[Canvas]

Algebra for generating a stream of events giving the current mouse location. Whenever the mouse moves a new event is generated. The algebra applies to a Renderer's Canvas data type instead of the F data type, and hence gives the mouse location in the canvas rather than relative to any Picture rendered on the canvas.
