+
+        * dispextern.h (struct glyph_slice): New struct.
+        (struct glyph): New member slice.
+        (GLYPH_SLICE_EQUAL_P): New macro.
+        (GLYPH_EQUAL_P): Use it.
+        (struct glyph_string): New member slice.
+        (struct it_slice): New struct.
+        (struct it): New member slice, add member to stack too.
+        New member constrain_row_ascent_descent_p.
+        (image_ascent): Add prototype.
+
+        * dispnew.c (buffer_posn_from_coords): Return full image width
+        and height even for image slices (posn is relative to full image).
+        (marginal_area_string): Adjust x0,y0 for image slice.
+
+        * image.c (image_ascent): Add slice arg; calculate ascent for
+        image slice (or full image).
+
+        * keyboard.c (Fposn_at_x_y, Fposn_at_point): New defuns.
+        (syms_of_keyboard): Defsubr them.
+
+        * lisp.h (pos_visible_p): Fix prototype.
+
+        * macterm.c (x_draw_relief_rect):  Add top_p and bot_p args.
+        (x_draw_glyph_string_box): Fix call to x_draw_relief_rect.
+        (x_draw_image_foreground, x_draw_image_relief)
+        (x_draw_image_foreground_1, x_draw_image_glyph_string):
+        Draw sliced images.
+
+        * w32term.c (w32_draw_relief_rect): Add top_p and bot_p args.
+        (x_draw_glyph_string_box): Fix call to x_draw_relief_rect.
+        (x_draw_image_foreground, x_draw_image_relief)
+        (w32_draw_image_foreground_1, x_draw_image_glyph_string):
+        Draw sliced images.
+
+        * w32term.h (image_ascent): Remove prototype.
+
+        * window.c (Fpos_visible_in_window_p): Return pixel position if
+        PARTIALLY arg is non-nil.  Simplify.  Doc fix.
+        (Fwindow_vscroll, Fset_window_vscroll): Add optional PIXEL_P arg
+        to return/set vscroll in pixels.
+
+        * window.h (Fwindow_vscroll, Fset_window_vscroll): Fix EXFUN.
+
+        * xdisp.c (Qslice): New variable.
+        (syms_of_xdisp): Intern and staticpro it.
+        (pos_visible_p): Return pixel position in new x and y args.
+        (init_iterator): Reset it->slice info.
+        (handle_display_prop): Parse (slice ...) property.
+        (push_it, pop_it): Save/restore slice info.
+        (make_cursor_line_fully_visible): Fix 2004-04-14 change.  Do not
+        force repositioning of tall row if window is vscrolled, as that
+        would reset vscroll.
+        (append_space): Set it->constrain_row_ascent_descent_p to avoid
+        increasing row height if row is non-empty.
+        (fill_image_glyph_string): Copy slice info.
+        (take_vertical_position_into_account): Simplify.
+        (produce_image_glyph): Handle iterator slice info, setup glyph
+        slice info.  Do not force minimum line height.
+        (x_produce_glyphs): If it->constrain_row_ascent_descent_p is set,
+        do not increase height (ascent/descent) of non-empty row when
+        adding normal character glyph; instead reduce glyph ascent/descent
+        appropriately; if row is higher than current glyph, adjust glyph
+        descent/ascent to reposition glyph within the existing row.
+        Likewise, when char is newline, only set ascent/descent if row is
+        currently empty.
+        (note_mouse_highlight): Handle hotspots with sliced image.
+
+        * xterm.c (x_draw_relief_rect): Add top_p and bot_p args.
+        (x_draw_glyph_string_box): Fix call to x_draw_relief_rect.
+        (x_draw_image_foreground, x_draw_image_relief)
+        (x_draw_image_foreground_1, x_draw_image_glyph_string):
+        Draw sliced images.
+
+        * xterm.h (image_ascent): Remove prototype.

         * fns.c (Fassoc, Feql): Fix indentation.
