Patch from Rob Adams addresses #95014 (placement issues), makes first fit

Browse Source 
2003-02-23  Havoc Pennington  <hp@pobox.com>

	Patch from Rob Adams addresses #95014 (placement issues),
	makes first fit algorithm "center tile", adds most code
	for per-xinerama workspaces (#86682) but disables it for now.

	* src/workspace.c (meta_workspace_get_work_area_for_xinerama)
	(meta_workspace_get_work_area_all_xineramas): new xinerama
	functions, maintain workspace->work_areas with a different
	work area for each xinerama. However for now all the work
	areas are the same, because haven't quite figured out how
	_NET_WM_STRUT is supposed to work

	* src/window.c: adapt to new meta_window_* xinerama APIs
	(meta_window_get_work_area_current_xinerama): new xinerama
	API
	(meta_window_get_work_area_for_xinerama): new xinerama API
	(constrain_position): be a bit more clever about which xinerama's
	work area we choose to use.

	* src/stack.c: adapt to new Xinerama API

	* src/screen.c (reload_xinerama_infos): invalidate all work areas
	(meta_screen_get_xinerama_for_rect): new function
	(meta_screen_window_intersects_xinerama): new function

	* src/place.c (find_first_fit): change to use
	"center tiling" (center a screen full of tiled windows,
	rather than aligning them top left). Adapt to new
	xinerama functions.
