Note: Web authors may use originX and originY in the way they deem most appropriate for the context of their application. In most cases, web applications receiving zoomrequest events will center the UI "zoom" on the originX/originY coordinates if they are provided. If origin coordinates are not provided, such as in the case of a keyboard-only zoom event, web authors will likely center the UI "zoom" in the middle of the receiving view.
