Thomas Fitzsimmons a605da04c1 Add _NET_FRAME_EXTENTS and _NET_REQUEST_FRAME_EXTENTS.
2004-01-09  Thomas Fitzsimmons  <fitzsim@redhat.com>

	Add _NET_FRAME_EXTENTS and _NET_REQUEST_FRAME_EXTENTS.

	* src/display.c: include xprops.h
	(process_request_frame_extents): new function
	(meta_display_open): add _NET_FRAME_EXTENTS and
	_NET_REQUEST_FRAME_EXTENTS atoms
	(event_callback): handle frame extents message

	* src/display.h (struct _MetaDisplay): add atom_net_frame_extents
	and atom_net_request_frame_extents

	* src/theme.c (meta_pango_font_desc_get_text_height): make font_desc
	parameter const

	* src/ui.c: include prefs.h
	(meta_ui_theme_get_frame_borders): new function

	* src/window.c (update_net_frame_extents): new function
	(meta_window_move_resize_internal): update frame extents
	property when frame geometry changes

	* src/screen.c (set_supported_hint): add atom_net_frame_extents
	and atom_net_request_frame_extents
