on unminimize, queue calc_showing on all transients

Browse Source 
2002-05-05  Havoc Pennington  <hp@pobox.com>

	* src/window.c (meta_window_unminimize): on unminimize, queue
	calc_showing on all transients
	(meta_window_activate): on activate, unminimize all a window's
	ancestors, not just the window itself.

	* src/workspace.c (set_work_area_hint): don't increment "tmp" by
	16 unsigned long, increment by 4

	* src/window.c (meta_window_free): if a window isn't minimized,
	restore its WM_STATE to NormalState instead of IconicState,
	since IconicState on initial window map means that the window
	should be minimized.

	* src/workspace.c (meta_workspace_invalidate_work_area): queue an
	idle to recompute the work area hint.
	(set_work_area_hint): we need 4*num_workspaces ints, not just
	num_workspaces.

	* src/screen.c (meta_screen_new): add work_area_idle field,
	handle it on screen shutdown

	* src/common.h (META_PRIORITY_PREFS_NOTIFY,
	META_PRIORITY_WORK_AREA_HINT): define some idle priorities

	* src/window.c (meta_window_calc_showing): hide windows if
	their parent window is minimized
	(meta_window_minimize): also queue_calc_showing on all
	transients of the window being minimized

	* src/place.c (constrain_placement): function to apply
	placement-time-only constraints, such as "not off the left of the
	screen"
	(meta_window_place): put dialogs down a bit over their parent,
	not right at the top.
	(meta_window_place): when centering a dialog, center it
	on the current xinerama screen, rather than the entire
	screen.

	* src/screen.c (meta_screen_get_current_xinerama): new function,
	but not implemented
