iterator stack (instead of hardcoded number). Increase from 2 to 4
to make room for propertized overlay strings before and after a
display string, image or composition.
(struct it): Add image_id and method members to iterator stack.
overlay_string_index after pop_it. Add asserts.
(handle_stop): Look for overlay strings around a display string,
image, or composition. Handle properties on those strings.
(next_overlay_string): Don't set string, pos or method after pop_it.
(get_overlay_strings_1): Split from get_overlay_strings; don't
modify it if no overlay strings are found.
(get_overlay_strings): Use get_overlay_strings_1. Always set
it->string and it->method.
(push_it): Push it->image_id and it->method. Push it->object
instead of it->string if method is GET_FROM_IMAGE.
(pop_it): Pop it->image_id and it->method. Ppo it->object
instead of it->string if method is GET_FROM_IMAGE.
Reset it->current.string_pos if popped it->string is nil.
(reseat_1): Remove comment dated 19 May 2003. It expressed doubt
whether a given change was correct; but the change is correct.
Clear it->string_from_display_prop_p.
(set_iterator_to_next): Rely on it->method and it->image_id from
iterator stack, instead of setting them explicitly after pop_it.
(PERIODIC_PREEMPTION_CHECKING): Define to 1 iff EMACS_HAS_USECS.
(Vredisplay_preemption_period): New variable.
(syms_of_display): DEFVAR_LISP and initialize it.
(preemption_period, preemption_next_check): New variables.
(update_frame, update_single_window): Initialize them based on
Vredisplay_preemption_period if !force_p.
(update_window, update_frame_1): Use them to determine when to
check for input.

(ispell-async-processp): Check for `delete-process' existence
instead of `kill-process' one for consistency.
