Gestures is an object that can recognize user gestures that form configurable shapes. It can listen to events of the user moving the mouse forming known gesture shapes. The object can recognize custom gesture shapes defined by a list of vertex points of the shape. A given callback function is invoked when the object recognizes a known user gesture shape. The object can also draw the gesture shape as the user moves the mouse.
xLayers animates page elements stacked in different layers. It traverses the list of page elements of a given container element and changes their positioning properties so they appear stacked as layers on top of each other. Some elements may be explicitly excluded from becoming layers. The position and size of each layer can be adjusted by the user with the mouse or animated automatically at a given timing rate.
