* Function for receiving input events from the browser.
*
* In order to receive input events, you must register for them by calling
* PPB_InputEvent.RequestInputEvents() or RequestFilteringInputEvents(). By
* default, no events are delivered.
*
* In general, you should try to keep input event handling short. Especially
* for filtered input events, the browser or page may be blocked waiting for
* you to respond.
*
* The caller of this function will maintain a reference to the input event
* resource during this call. Unless you take a reference to the resource
* to hold it for later, you don't need to release it.
*
* @return PP_TRUE if the event was handled, PP_FALSE if not. If you have
* registered to filter this class of events by calling
* RequestFilteringInputEvents, and you return PP_FALSE, the event will
* be forwarded to the page (and eventually the browser) for the default
* handling. For non-filtered events, the return value will be ignored.
