Ot_page_transition.Makeinstall_global_handler t take_screenshot animation_type creates a global onchangepage handler which is registered recursively and applies to all pages. t is the transition duration of the animation. take_screenshot callback takes a screenshot of the current page and then calls callback. A callback function is used here because take_screenshot is usually asynchronous. animation_type ev decides the type of the animation of page transition in an onchangepage event.
TODO: we can avoid the callback function by transforming take_screenshot to a function of type unit -> screenshot Lwt.t
