Unified mouse, mouse wheel & single-touch event stream abstraction. Stream emits tuples of:
[type, {pos, click?, delta?, zoom}]
The click and delta values are only present if type == GestureType.DRAG. Both (and pos too) are 2-element arrays of [x,y]
coordinates.
The zoom value is always present, but is only updated with wheel
events. The value will be constrained to minZoom ... maxZoom
interval (provided via options object).
