mutter/src/theme.h
Thomas James Alexander Thurman 90359a5346 Added "above" to the list of flags a frame can have, so that we know when 
* common.h: Added "above" to the list of flags a frame can have, so
	that we know when to mark it as always on top.  Added six grab ops,
	one to do and one to undo each of the three new titlebar buttons
	(shade, above, stick).  Added six new button functions, similarly.
	(#96229)

        * frame.c (meta_frame_get_flags): If a frame has the WM_STATE_ABOVE X
         attribute, set META_FRAME_ABOVE in its flags.

        * frames.c (meta_frames_apply_shapes): Allow variable amounts of
         rounding. (#113162)

        * frames.c (show_tip_now, meta_frames_paint_to_drawable, control_rect,
	 get_control): extend handling of existing buttons to the
         3*2 new kinds of button. (#96229)

        * frames.c (meta_frames_button_press_event): translate clicks on the 3*2
         new kinds of button to the new grab ops. (#96229)

        * frames.c (meta_frames_button_release_event): implement the various
        actions for the 3*2 new kinds of button. (#96229)

        * frames.c (meta_frames_update_prelit_control,
         meta_frames_motion_notify_event): extend existing motion
         notifications for buttons to the 3*2 new kinds of button. (#96229)

        * frames.c (meta_frames_set_window_background): handle specified
         background colours and alpha transparency. (#151261)

        * frames.h (MetaFrameControl): New control types for the 3*2 new kinds
	 of button.  (#96229)

        * iconcache.[ch] (meta_read_icons): use theme's fallback icons if a
	 window has no icon; use metacity's fallback icons only if the theme
         does not provide any. (#11363)

        * iconcache.[ch] (meta_invalidate_default_icons (new function)): clear
         icon cache on windows using default icons, and update them. (#11363)

	 types. (#96229)

         function's inverse (shade -> unshade, etc) (#96229)

        * theme-parser.c (parse_rounding (new function)): parse window
	 rounding amount (#113162)

        * theme-parser.c (parse_alpha): don't set error if the number can't
	 be parsed since it'll already be set; change tolerance in comparison
	 from 1e6 to 1e-6

        * theme-parser.c (parse_color (new function)): parse colour, including
	 possible constant lookup.

        * theme-parser.c (parse_toplevel_element): allow defining of various
	new kinds of constant; allow
