redeem_scrollbar_hook, judge_scrollbars_hook): Removed dumbo "externs" from these. They're supposed to be real definitions. * termhooks.h (mouse_position_hook): Doc fix. (set_vertical_scrollbar_hook): This doesn't return anything any more, and doesn't take a struct scrollbar * argument any more. (condemn_scrollbars_hook, redeem_scrollbar_hook, judge_scrollbars_hook): Doc fixes. * term.c (mouse_position_hook): Doc fix. (set_vertical_scrollbar_hook): This doesn't return anything any more. Doc fixes. * keyboard.c (kbd_buffer_get_event): Receive the scrollbar's window from *mouse_position_hook and pass it to make_lispy_movement, instead of working with a pointer to a struct scrollbar. (make_lispy_event): We don't need a window_from_scrollbar function anymore; we are given the window directly in *EVENT. Unify the code which generates text-area mouse clicks and scrollbar clicks; use the same code to distinguish clicks from drags on the scrollbar as in the text area. Distinguish clicks from drags by storing a copy of the lispy position list returned as part of the event. (button_down_location): Make this a lisp vector, rather than an array of random structures. (struct mouse_position): Remove this; it's been replaced by a lisp list. (make_lispy_movement): Accept the scrollbar's window as a parameter, rather than the scrollbar itself. If FRAME is zero, assume that the other arguments are garbage. (syms_of_keyboard): No need to staticpro each window of button_down_location now; just initialize and staticpro it. * window.c (window_from_scrollbar): Function deleted; no longer needed. * xdisp.c (redisplay_window): Just pass the window to set_vertical_scrollbar hook; don't pass the scrollbar object too. * xterm.c (XTmouse_position): Don't return a pointer to the scrollbar for scrollbar motion; instead, return the scrollbar's window.
