//
// Why do we have to rely on proximity?
//
// Because the target of the touch event that triggered the vclick
// can be different from the target of the click event synthesized
// by the browser. The target of a mouse/click event that is synthesized
// from a touch event seems to be implementation specific. For example,
// some browsers will fire mouse/click events for a link that is near
// a touch event, even though the target of the touchstart/touchend event
// says the user touched outside the link. Also, it seems that with most
// browsers, the target of the mouse/click event is not calculated until the
// time it is dispatched, so if you replace an element that you touched
// with another element, the target of the mouse/click will be the new
// element underneath that point.
//
// Aside from proximity, we also check to see if the target and any
// of its ancestors were the ones that blocked a click. This is necessary
// because of the strange mouse/click target calculation done in the
// Android 2.1 browser, where if you click on an element, and there is a
// mouse/click handler on one of its ancestors, the target will be the
// innermost child of the touched element, even if that child is no where
// near the point of touch.
