mouse-input

mouse-input-test exercises mouse input through a child view (in this case, the mouse-input-view Dart component) and asserting the location as well as what button was used (mouse down, mouse up, wheel, etc) during the event. We do this by attaching the child view, injecting mouse input, and validating that the view reports the event back with the expected payload.
