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).
