Make scrollbar structures into lisp objects, so that they can be
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.
(SCROLLBAR_VEC_SIZE, XSCROLLBAR, SCROLLBAR_PACK, SCROLLBAR_UNPACK,
SCROLLBAR_X_WINDOW, SET_SCROLLBAR_X_WINDOW,
VERTICAL_SCROLLBAR_INSIDE_WIDTH, VERTICAL_SCROLLBAR_TOP_RANGE,
VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
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.
[MULTI_FRAME and not MULTI_FRAME] (FRAME_SCROLLBARS,
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
field.
(x_scrollbar_create, x_scrollbar_set_handle, x_scrollbar_move,
x_scrollbar_remove, XTset_vertical_scrollbar,
XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,
x_scrollbar_expose, x_scrollbar_handle_click,
x_scrollbar_handle_motion): Substantially rewritten to correct
typos and brainos, and to accomodate the lispy structures.
