/**
* The default "idle" tool. If no tool is active, or the active tool does not respond to a given
* event, input events are forwarded to the idle tool. The default idle tool converts middle mouse button events
* and touch gestures into view navigation operations like pan, zoom, rotate, and fit.
*
* Controls are as follows:
* - Mouse/keyboard:
* - mmb: pan
* - shift-mmb: rotate
* - wheel: zoom in/out
* - double-mmb: fit view
* - Touch:
* - single-finger drag: rotate
* - two-finger drag: pan
* - pinch: zoom in/out
* - double-tap: fit view
*
* Touch inputs can be combined e.g. drag two fingers while moving them closer together => pan + zoom in
* @public
