/* This file defines Emscripten low-level glue bindings for interfacing with the following HTML5 APIs:
* - DOM Level 3 Events: Keyboard, Mouse, Mouse Wheel, Resize, Scroll, Focus. See https://dvcs.w3.org/hg/dom3events/raw-file/tip/html/DOM3-Events.html
* - DeviceOrientation Events for gyro and accelerometer. See http://www.w3.org/TR/orientation-event/
* - Screen Orientation Events for portrait/landscape handling. See https://dvcs.w3.org/hg/screen-orientation/raw-file/tip/Overview.html
* - Fullscreen Events for browser canvas fullscreen modes transitioning. See https://dvcs.w3.org/hg/fullscreen/raw-file/tip/Overview.html
* - Pointer Lock Events for relative-mode mouse motion control. See http://www.w3.org/TR/pointerlock/
* - Vibration API for mobile device haptic vibration feedback control. See http://dev.w3.org/2009/dap/vibration/
* - Page Visibility Events for power management control. See http://www.w3c-test.org/webperf/specs/PageVisibility/
* - Touch Events. See http://www.w3.org/TR/touch-events/
* - Gamepad API. See http://www.w3.org/TR/gamepad/
* - Beforeunload event. See http://www.whatwg.org/specs/web-apps/current-work/multipage/history.html#beforeunloadevent
* - WebGL context events. See http://www.khronos.org/registry/webgl/specs/latest/1.0/#5.15.2
*
* Most web APIs are event-based, which means that the functionality is accessed by registering a callback function to be called when the event occurs. The
* Gamepad API is currently an exception, for which only a polling API is available. For some APIs, both an event-based and a polling-based API is exposed.
*
* Calling a callback registration function with a null pointer function causes an unregistration of that callback from the given target element. All event
* handlers are also automatically unregistered when the C exit() function is invoked during the atexit handler pass. Use either the function
* emscripten_set_main_loop() or set Module.noExitRuntime = true; to make sure that leaving main() will not immediately cause an exit() and clean up the
* event handlers.
*
* Throughout this file, the function signatures have a 'target' parameter. This parameter allows specifying the HTML Element ID to which the callback
* registration is to be applied to. This field has the following special meanings:
* - 0 or NULL: A default element is chosen automatically based on the event type, which should be reasonable most of the time.
* - "#window": The event listener is applied to the JS 'window' object.
* - "#document": The event listener is applied to the JS 'document' object.
* - "#screen": The event listener is applied to the JS 'window.screen' object.
* - "#canvas": The event listener is applied to the Emscripten default WebGL canvas element.
* - Any other string without a leading hash "#" sign: The event listener is applied to the element by the given ID on the page.
*
* The callback hook functions also take in a 'userData' parameter. This is a custom user-defineable value that will be carried through unchanged to all
* invocations of the registered event callback. Use this e.g. to pass a pointer to a C++ class or similar to enclose the C API in a clean object-oriented manner.
*
* Callback handlers that return an EM_BOOL may return nonzero to signal that the default action for that event is to be suppressed. This will call
* the .preventDefault(); member on the event. Returning zero will cause the default browser event action to be carried out.
*
* Most functions return the result using the type EMSCRIPTEN_RESULT. Nonzero and positive values denote success. Negative values
* signal failure. None of the functions fail or abort by throwing a JS or C++ exception. If a particular browser does not support the given feature,
* the value EMSCRIPTEN_RESULT_NOT_SUPPORTED will be returned at the time the callback is registered.
*
* Due to web security purposes, the pointer lock and fullscreen requests can only be invoked from inside an user-originated event handler. Such requests
* are automatically deferred until the user presses a keyboard or mouse button the next time.
