### Is your feature request related to a problem? Please describe. For documentation purposes BPMN.io is used to show BPMN processes in normal and fullscreen mode. In normal mode the modules [MoveCanvas](https://github.com/bpmn-io/diagram-js/blob/develop/lib/navigation/movecanvas/MoveCanvas.js) and [ZoomScroll](https://github.com/bpmn-io/diagram-js/blob/develop/lib/navigation/zoomscroll/ZoomScroll.js) should be disabled and in fullscreen mode these modules should be enabled. [ZoomScroll has the toggle method](https://github.com/bpmn-io/diagram-js/blob/develop/lib/navigation/zoomscroll/ZoomScroll.js#L216), this method is missing in the [MoveCanvas module](https://github.com/bpmn-io/diagram-js/blob/develop/lib/navigation/movecanvas/MoveCanvas.js) ### Describe the solution you'd like Add a toggle method to the [MoveCanvas module](https://github.com/bpmn-io/diagram-js/blob/develop/lib/navigation/movecanvas/MoveCanvas.js) as a non breaking change to enable and disable the canvas movement dynamicly. ### Describe alternatives you've considered The [ReadOnly module](https://gist.github.com/adbre/2353693cb40e0af0404613e52f87d05b) is something similar but feels like a very drastic hack. ### Context I am willing to sponsor this feature
