2003-10-12  Havoc Pennington  <hp@redhat.com>

        Merge reduced_resources mode patch from the branch. Offers
	wireframe and no-animations.

	* src/window.c (implement_showing): no animation if we are
	in reduced resources mode

	* src/prefs.c: add REDUCED_RESOURCES pref

	* src/window.c (meta_window_update_keyboard_resize): fix to
	modify grab_anchor_window_pos to grab_wireframe_rect if
	appropriate instead of window->rect

	* src/display.h (struct _MetaDisplay): add grab_start_serial used
	to avoid responding to events that occurred prior to the grab
	initialization.

	Still broken in various ways, specifically EnterNotify that
	occurred prior to XGrabPointer is processed as if it occurred
	after.

	* src/window.c (meta_window_update_keyboard_move): add this
	instead of meta_window_warp_pointer() crack

	* src/effects.c (meta_effects_update_wireframe): draw a kind of
	grid for the wireframe, instead of just a rectangle, like twm

	* src/screen.c (meta_screen_new): line width of 3 for the XOR gc

        "Reduced resources" mode based on wireframe patch from
	Erwann Chenede. Still pretty buggy.

	* src/keybindings.c (process_keyboard_move_grab)
	(process_keyboard_resize_grab): add gruesome wireframe hacks

	* src/display.c (meta_display_end_grab_op): end wireframe
	(meta_display_begin_grab_op): begin wireframe

	* src/effects.c (meta_effects_end_wireframe)
	(meta_effects_update_wireframe, meta_effects_begin_wireframe):
	routines to draw the wireframe stuff

	* src/window.c (window_should_be_showing): hide window when
	doing wireframe, commented out as it breaks grab
	* src/window.c (meta_window_refresh_resize_popup): handle wireframe

	* src/screen.c (meta_screen_new): create a screen->root_xor_gc
	for use in drawing wireframes

	* src/frames.c (meta_frames_push_delay_exposes): repaint
	everything before we delay
