      Speed up cursor motion in large fontified buffers. · e8c17b88
      Eli Zaretskii authored
       src/xdisp.c (reseat): Don't look for prev_stop, as that could mean a
       very long run.
       (next_element_from_buffer): When iterator oversteps prev_pos
       backwards, don't search for a new prev_stop more than 1000
       characters back.
       (handle_stop_backwards): Don't assume that CHARPOS is necessarily
       a stop_pos.
       (compute_display_string_pos): Check also BUF_OVERLAY_MODIFF for a
       match, when testing the cached display string position for
       applicability.

       (move_it_in_display_line_to): If iterator ended up at
       EOL, but we never saw any buffer positions smaller than
       to_charpos, return MOVE_POS_MATCH_OR_ZV.  Fixes vertical cursor
       motion in bidi-reordered lines.

      GLYPH_DEBUG fixes · 85fece3e
      Paul Eggert authored
      The following patches are for when GLYPH_DEBUG && !XASSERT.
      * dispextern.h (trace_redisplay_p, dump_glyph_string):
      * dispnew.c (flush_stdout):
      * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
      Mark as externally visible.
      * dispnew.c (check_window_matrix_pointers): Now static.
      * dispnew.c (window_to_frame_vpos):
      * xfns.c (unwind_create_frame):
      * xterm.c (x_check_font): Remove unused local.
      * scroll.c (CHECK_BOUNDS):
      * xfaces.c (cache_fache): Rename local to avoid shadowing.
      * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
      * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
      (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
      (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
      Now static.
      (debug_method_add): Use va_list and vsprintf rather than relying
      on undefined behavior with wrong number of arguments.
      (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
      Don't assume ptrdiff_t and EMACS_INT are the same width as int.
      In this code, it's OK to assume C99 behavior for ptrdiff_t formats
      since we're not interested in debugging glyphs with old libraries.
      * xfaces.c (cache_face): Move debugging code earlier; this pacifies
      GCC 4.6.0's static checking.
