Rework the click-client-area-to-focus support to use synchronous grabs,
2001-12-10 Havoc Pennington <hp@pobox.com>
Rework the click-client-area-to-focus support to use synchronous
grabs, avoids a big mess, lets us pass through click when
required (for dock/desktop). Disadvantage is all left-button
clicks now require window manager approval. ;-)
* src/display.c (event_callback): don't focus dock/desktop when
the mouse enters them; require a click.
(meta_change_button_grab): allow sync grabs
(meta_display_grab_unfocused_window_buttons): establish a
synchronous grab and maintain it all the time, rename to
meta_display_grab_focus_window_button
* src/window.c: change to reflect display.c
