+ 
+       The following changes serve several purposes:
+ 
+       1) Swap the position of fringes and display margins in windows, i.e.
+       the fringes are now displayed between the margins and the text area
+       (by default).
+ 
+       2) Allow fringe and scroll bar parameters to be set per-buffer and
+       per-window (like display margins).  Such settings are now stored
+       in window configurations, preserved when frames are resized, and
+       copied when windows are split vertically or horisontally.
+       Several bugs related to display margins have been fixed.
+ 
+       3) Consistently use FRAME_FONT and FRAME_FONTSET macros.
+       
+       4) Use FRAME_COLUMN_WIDTH (f) consistently throughout the code
+       rather than FRAME_WIDTH (FRAME_FONT (f)).
+ 
+       5) Introduce a consistent naming of variables, members and macros
+       depending on whether their value is measured in pixels or in
+       canonical columns/lines.  Pixel dimensions are named *_width and
+       *_height, while canonical columns/lines are named *_cols and
+       *_lines.  Pixel positions are named *_x and *_y, while column/line
+       positions are named *_col and *_line.
+ 
+       6) Consolidate more of the X, W32, and MAC gui code by moving
+       common data into struct frame, and generalize it for the non-gui
+       case by using suitable defaults.
+ 
+       7) Cleanup and consolidate the macros controlling frame and window
+       layout into frame.h and window.h, and generalize the use of the
+       various window_box_* functions (enhanced to handle the new fringe
+       position and the per-window fringe and scroll bar settings).
+ 
+       * frame.h (struct frame): Rename members height to text_lines,
+       width to text_cols, window_height to total_lines, window_width to
+       total_cols, new_height to new_text_lines, new_width to
+       new_text_cols.  All uses changed.
+       (struct frame): New members which consolidate common members of
+       x_output, w32_output, and mac_output structures: left_pos,
+       top_pos, pixel_height, pixel_width, x_pixels_diff, y_pixels_diff,
+       win_gravity, size_hint_flags, border_width, internal_border_width,
+       line_height, fringe_cols, left_fringe_width, right_fringe_width,
+       want_fullscreen.  All uses changed.
+       (struct frame): New member column_width contaning the canonical
+       column width, analogue to line_height.  All uses changed.
+       (struct frame): Rename members scroll_bar_pixel_width to
+       config_scroll_bar_width, and scroll_bar_cols to
+       config_scroll_bar_cols.  All uses changed.
+       (struct frame): New member scroll_bar_actual_width which
+       consolidates and renames the vertical_scroll_bar_extra member of
+       x_output, w32_output, and mac_output structures.  All uses changed.
+       (FRAME_PIXEL_HEIGHT): Renamed from PIXEL_HEIGHT and moved
+       from x/w32/macterm.h files.  All uses changed.  Also change code
+       which referred to f->output_data...->pixel_height.
+       (FRAME_PIXEL_WIDTH): Renamed from PIXEL_WIDTH and moved

+       scroll_bar_width, and vertical_scroll_bar_type.
+       (syms_of_buffer): Defvar_per_buffer them, and defvar_lisp_nopro
+       default-* variables for them.
+ 
+       * dispnew.c: Make (many) trivial substitutions for renamed and
+       new macros in dispextern.h, frame.h and window.h.

+       is already adjusted by the caller.
+       (marginal_area_string): Handle fringes inside/outside margins.
+       
+       * frame.c: Make (many) trivial substitutions for renamed and
+       new macros in dispextern.h, frame.h and window.h.
+       (make_frame): Initialize left_fringe_width, right_fringe_width,
+       fringe_cols, scroll_bar_actual_width, border_width,

+       y_pixels_diff, want_fullscreen, size_hint_flags, and win_gravity
+       members with values suitable for a non-window frames.
+ 
+       * gtkutil.c: Make (many) trivial substitutions for renamed and

+ 
+       * keyboard.c: Make (many) trivial substitutions for renamed and
+       new macros in dispextern.h, frame.h and window.h.
+       (make_lispy_event): Use window positions returned from
+       window_from_coordinates when constructing the lisp event for
+       MOUSE_CLICK_EVENT and DRAG_N_DROP_EVENT, rather than calculating
+       (incorrect) values locally.
+       (make_lispy_movement): Use window positions returned from
+       window_from_coordinates when constructing the lisp event, rather
+       than calculating (incorrect) values locally.

+       new macros in dispextern.h, frame.h and window.h.
+ 
+       * sunfns.c (Fsun_menu_internal): Adapt to per-window fringes and
+       scroll-bars.
+ 
+       * sysdep.c: Make (few) trivial substitutions for renamed and
+       new macros in dispextern.h, frame.h and window.h.
+ 
+       * term.c: Make (some) trivial substitutions for renamed and
+       new macros in dispextern.h, frame.h and window.h.

+       (make_window): Initialize new members
+       left_margin_cols, right_margin_cols, left_fringe_width,
+       right_fringe_width, fringes_outside_margins, scroll_bar_width,
+       and vertical_scroll_bar_type.
+       (coordinates_in_window): Adapted to new fringe/margin positions
+       and per-window fringes and scroll-bars.  
+       Fix bug related to incorrectly adjusting coordinates by
+       frame's internal_border_width (the effect normally negible since 
+       the internal_border_width is typically 0 or 1 pixel, but very
+       noticeable for an internal_border_width of e.g. 25 pixels).
+       Upon successful return (other than ON_NOTHING), the coordinates
+       are now always properly converted to window relative for the
+       given display element.
+       (window_from_coordinates): Add new parameters wx and wy to
+       return the window relative x and y position in the returned
+       window and part.  A null arg means, don't return the position.
+       All callers changed.
+       (adjust_window_margins): New function which may reduce the width
+       of the display margins if a window's text area is too small after
+       resizing or splitting windows.
+       (size_window): Fix bug that did not account for display margin
+       widths when checking the minimum width of a window; use
+       adjust_window_margins.
+       (set_window_buffer): Call Fset_window_fringes and
+       Fset_window_scroll_bars to setup per-window elements.
+       Add new arg KEEP_MARGINS_P.  Non-nil means to keep window's
+       existing display margin, fringe widths, and scroll bar settings
+       (e.g. after splitting a window or resizing the frame).  All
+       callers changed.
+       (Fset_window_buffer): New arg KEEP_MARGINS.  All callers changed.
+       (Fsplit_window): Duplicate original window's display margin,
+       fringe, and scroll-bar settings; then call Fset_window_buffer with
+       KEEP_MARGINS non-nil.  This fixes a bug which caused a split
+       window to only preserve the display margins in one of the windows.
+       When splitting horisontally, call adjust_window_margins on both
+       windows to ensure that the text area of the new windows is non too
+       narrow.  This fixes a bug which could cause emacs to trap if the
+       width of the split window was less than the width of the display
+       margins.
+       (window_box_text_cols): Renamed from window_internal_width.  All
+       uses changed.  Adapt to per-window fringes and scroll bars.
+       Fix bug that caused vertical separator to be subtracted also on
+       window frames.  Fix another bug that did not reduce the returned
+       value by the columns used for display margins.
+       (window_scroll_line_based): Fix bug related to scrolling too much
+       when display margins are present (implicitly fixed by the fix to
+       window_box_text_cols).
+       (scroll_left, scroll_right): Fix bug related to scrolling too far
+       by default when display margins are present (implicitly fixed by
+       the fix to window_box_text_cols).
+       (struct saved_window): Rename members left to left_col, top to
+       top_line, width to total_cols, height to total_lines, orig_top to
+       orig_top_line, orig_height to orig_total_lines.  All uses changed.
+       New members left_margin_cols, right_margin_cols,
+       left_fringe_width, right_fringe_width, fringes_outside_margins,
+       scroll_bar_width, and vertical_scroll_bar_type for saving
+       per-window display elements.
+       (Fset_window_configuration): Restore display margins, fringes,
+       and scroll bar settings.  This fixes a bug which caused display
+       margins to be discarded when saving and restoring a window
+       configuration.
+       (save_window_save): Save display margins, fringes, and scroll bar
+       settings.  This fixes a bug which caused display margins to be
+       discarded when saving and restoring a window configuration.
+       (Fset_window_margins): Do nothing if display margins are not
+       really changed.  Otherwise, call adjust_window_margins to ensure
+       the text area doesn't get too narrow.  This fixes a bug which
+       could cause emacs to trap if setting display margins wider than
+       the width of the window.
+       (Fset_window_fringes): New defun to allow user to specifically set
+       this window's fringe widths and position vs. display margins.

+       settings.
+       (Fset_window_scroll_bars): New defun to allow user to specifically
+       set this window's scroll bar width and position.

+       bar settings.

+       (window_box_width): Adapt to per-window fringes and scroll bars,
+       and new fringe vs. display margin position. Note that returned
+       value is no longer guaranteed to be a whole multiple of the frame
+       column width, since per-window fringes may now be any width.
+       (window_box_left_offset): New function like window_box_left, but
+       value is relative to left border of window (rather than frame).
+       (window_box_right_offset): New function like window_box_right,
+       but value is relative to left border of window.
+       (window_box_left): Adapt to per-window fringes and scroll bars,
+       and new fringe vs. display margin position.  Simplify by using
+       WINDOW_LEFT_EDGE_X and window_box_left_offset.

+       change/simplify relevant callers.
+       (x_y_to_hpos_vpos): Adapt to per-window fringes and scroll bars,
+       and new fringe vs. display margin position.  Use

+       scroll bars, and new fringe vs. display margin position.  Use

+       (draw_fringe_bitmap): Rework to handle per-window fringes and new
+       fringe vs. display margin position.
+       (hscroll_window_tree): Use window_box_width instead of window_box.
+       (redisplay_window):  Adapt to per-window scroll bars.
+       (draw_glyphs):  Rework to handle per-window fringes and scroll
+       bars, and new fringe vs. display margin position.  Use
+       WINDOW_LEFT_EDGE_X, WINDOW_TOTAL_WIDTH, and window_box_left.
+       (x_clear_end_of_line):  Adapt to per-window fringes and scroll
+       bars, and new fringe vs. display margin position.  Fix bug which
+       increased total width of full_width rows by width of scroll bars
+       although window's total width already includes that.
+       (x_fix_overlapping_area): Simplify using window_box_left_offset.
+       (expose_area): Simplify using window_box_left_offset.
+       (x_draw_vertical_border): Handle per-window scroll bar settings,
+       mixing windows with left, right and no scroll bars.

+       (handle_one_xevent): Simplify a USE_GTK conditional.

+       (x_new_font): Set FRAME_COLUMN_WIDTH and FRAME_LINE_HEIGHT
+       directly, then call compute_fringe_widths.  Don't call
