      Make scrollbar structures into lisp objects, so that they can be · 7c299e7a
      Jim Blandy authored
      	GC'd; this allows windows and scrollbars can refer to each other
      	without worrying about dangling pointers.
      	* xterm.h (struct x_display): vertical_scrollbars and
      	judge_timestamp members deleted.
      	(struct scrollbar): Redesigned to be a template for a Lisp_Vector.
      	New macros, to help deal with the lispy structures, and deal with
      	the graphics.
      	* frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.
      	(struct frame): New fields `scrollbars' and
      	`condemned_scrollbars', for use by the scrollbar implementation.
      	FRAME_CONDEMNED_SCROLLBARS): Accessors for the new field.
      	* window.h (struct window): Doc fix for vertical_scrollbar field.
      	* frame.c (make_frame): Initialize the `scrollbars' and
      	`condemned_scrollbars' fields of the new frame.
      	* alloc.c (mark_object): Mark the `scrollbars' and
      	`condemned_scrollbars' slots of frames.
      	* xterm.c (x_window_to_scrollbar): Scrollbars are chained on
      	frames' scrollbar field, not their x.display->vertical_scrollbars
      	(x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,

      	x_scrollbar_expose, x_scrollbar_handle_click,
      	x_scrollbar_handle_motion): Substantially rewritten to correct
      	typos and brainos, and to accomodate the lispy structures.

      	Change the meaning of focus redirection to make switching windows
      	work properly.  Fredirect_frame_focus has the details.
      	* frame.h (focus_frame): Doc fix.
      	[not MULTI_FRAME] (FRAME_FOCUS_FRAME): Make this Qnil, which
      	indicates no focus redirection, instead of zero, which is
      	* frame.c (make_frame): Initialize f->focus_frame to Qnil, rather
      	than making it point to frame itself.

      	redirections being nil.
      	It's a pain to remember that you can't assign to FRAME->visible.
      	Let's change all references to the `visible' member of struct
      	frame to use the accessor macros, and then write a setter for the
      	`visible' field that does the right thing.
      	* frame.h (FRAME_VISIBLE_P): Make this not an l-value.
