Havoc Pennington de42a62f4e Theme breakage! Themes have to implement "border" frames now, see Atlanta 
2002-06-21  Havoc Pennington  <hp@pobox.com>

        Theme breakage! Themes have to implement "border" frames
	now, see Atlanta for an example. Fixes #84285

	* src/tools/metacity-window-demo.c (do_appwindow): add a
	border-only window

	* src/window.c (update_mwm_hints): read border only from the MWM
	hints

	* src/window.h (struct _MetaWindow): add border_only flag

	* src/core.c (meta_core_get_frame_type): report border type if
	required

	* src/common.h (enum): add META_FRAME_TYPE_BORDER
