18. One or more computer-readable storage media storing instructions that, when executed via a computing device, cause the computing device to implement an dynamically compiled application configured to perform operations including: directing creation of a gesture object for a selected target element of content for the application to register for gesture detection via a script-based recognition interface exposed by a rendering engine of the computing device; obtaining gesture events fired on the target element by the gesture object that are indicative of gestures recognized based upon user interaction with the target element; tracking a state of the target element; applying the gesture events to the target element to manipulate display of the target element in accordance with the recognized gestures; and updating the state of the target element based on the applying.
