Enable mouse-wheel zooming

If selected, you can use Ctrl + MouseWheelForward (Command + MouseWheelForward on macOS) to increase the editor font (zoom in) or Ctrl + MouseWheelBackwards (Command + MouseWheelBackwards on macOS) to decrease the editor font (zoom out). It is enabled by default on Windows and Linux, while it is disabled by default on macOS, due to the way inertia affects the mouse wheel on this operating system.
