* Extend an event with additional view-specific methods.

* The vega object provides the following methods:
* view - Returns the backing View instance.
* item - Returns the currently active scenegraph item (if any).
* group - Returns the currently active scenegraph group (if any).
* This method accepts a single string-typed argument indicating the name
* of the desired parent group. The scenegraph will be traversed from
* the item up towards the root to search for a matching group. If no
* argument is provided the enclosing group for the active item is
* returned, unless the item it itself a group, in which case it is
* returned directly.
* xy - Returns a two-element array containing the x and y coordinates for
* mouse or touch events. For touch events, this is based on the first
* elements in the changedTouches array. This method accepts a single
* argument: either an item instance or mark name that should serve as
* the reference coordinate system. If no argument is provided the
* top-level view coordinate system is assumed.
* x - Returns the current x-coordinate, accepts the same arguments as xy.
* y - Returns the current y-coordinate, accepts the same arguments as xy.
* @param {Event} event - The input event to extend.
* @param {Item} item - The currently active scenegraph item (if any).
* @return {Event} - The extended input event.
