Elijah Newren 07e4cacf14 Patch from Carlo Wood to ensure that maximized and minimized properties 
2006-10-01  Elijah Newren  <newren gmail com>

	Patch from Carlo Wood to ensure that maximized and minimized
	properties are maintained across restarts.  #358042.

	* src/constraints.c (place_window_if_needed): fix up partial
	maximization handling and add minimize_after_placement handling.

	* src/display.[ch] (struct MetaDisplay, meta_display_open): add a
	new display->display_opening flag to allow handling startup
	differently where needed.

	* src/window-props.c (reload_net_wm_state): handle
	_net_wm_state_hidden as well, setting
	window->minimize_after_placement appropriately

	* src/window.[ch] (struct MetaWindow, meta_window_new_with_attrs):
	add a window->minimize_after_placement field

	* src/window.c (meta_window_new_with_attrs): only unminimize the
	window and its transients if the display isn't being opened,
	(unmaximize_window_before_freeing): don't reset the state unless
	the window is becoming withdrawn, if the screen is being closed be
	sure to save the unmaximized state of the window so the next
	window manager can restore it
