 * Helper function to see if the current render callback is rendering a water reflection.
 *
 * When the player is in a room with water, things will be rendered twice: once for the normal
 * rendering, and once for the reflecting rendering. Thus, any mod code in a render callback will
 * run twice per frame in these situations, which may be unexpected or cause bugs.
 *
 * This function is typically used to early return from a render function if it returns true.
