Allow the mouse wheel to zoom in and out of the application where applicable

Our mobile app generates a 3D render on the screen that you can rotate on the various axis and zoom in and out.

Currently on iPad devices I have no way of zooming out to view a design, if too big to fit on the screen, or zoom in, to look inside a design. I believe some of the other devices have, or had, some additional input options i.e. 2 finger pinch options but this hasn't been rolled out across all devices. A zoom functionality that is tied to the mouse wheel would be a nice option
