Wrap XSetInputFocus, making display->expected_focus_window a little more

Browse Source 
2004-12-22  Elijah Newren  <newren@gmail.com>

	Wrap XSetInputFocus, making display->expected_focus_window a
	little more reliable (see #154598)

	* src/display.h: (struct _MetaDisplay): add a large comment about
	the expected_focus_window, add a last_focus_time field,
	(XSERVER_TIME_IS_BEFORE): new macro moved from window.c but fixed
	for 64-bit systems, (meta_display_set_input_focus_window): new
	function

	* src/display.c (meta_display_open): initialize last_focus_time,
	add a comment about brokenness of trying to set intial focus
	window, (meta_display_set_input_focus_window): new function that
	wraps XSetInputFocus,
	(meta_display_focus_the_no_focus_window): make this function
	closer to a wrapping of XSetInputFocus for the no_focus_window.

	* src/window.c (XSERVER_TIME_IS_LATER): remove this macro in favor
	of the improved one added to display.h

	* src/display.c (meta_display_open):
	* src/window.c (meta_window_focus):
	use meta_display_focus_the_no_focus_window and
	meta_display_set_input_focus instead of XSetInputFocus
