+
+        * xdisp.c (move_it_by_lines): If we move forward after going too
+        far back, cancel move if end position is same as start position.

+
+        * dispextern.h (struct glyph_string): New members clip_head and
+        clip_tail.
+
+        * xdisp.c (get_glyph_string_clip_rect): Restrict horizontal clip
+        region to the area between clip_head and clip_tail.
+        (draw_glyphs): Record the area that need to be actually redrawn to
+        the new variables clip_head and clip_tail when there are
+        overhangs.  Set values of these variables to the corresponding
+        members in struct glyph_string.  Refine x coordinates for
+        notice_overwritten_cursor using clip_head and clip_tail.
+
+        * macgui.h (STORE_XCHARSETSTRUCT): New macro.
+
+        * macterm.c (mac_compute_glyph_string_overhangs): Implement with
+        QDTextBounds.
+        (x_draw_glyph_string): Don't fill the background of the successor
+        of a glyph with a right overhang if the successor will draw a cursor.
+        (XLoadQueryFont): Obtain font metrics using QDTextBounds.
+        (x_redisplay_interface): Add entry for compute_glyph_string_overhangs.

+
+        * window.c (window_scroll_pixel_based): Fix scrolling in the wrong
+        direction if window height was smaller than next-screen-context-lines.
+        Now always scroll at least one line in the requested direction.
+        Ensure that we actually do scroll backwards when requested to do so.
+
+        * xdisp.c (redisplay_window): Only try to make cursor line fully
+        visible once (to avoid redisplay loop).
+

+
+        * window.c (Fpos_visible_in_window_p): Simplify return value for
+        partially visible rows.
+        (window_scroll_pixel_based): Adapt to that change.
+
+        * window.c (window_scroll_pixel_based): Force moving to next line
+        if scrolling doesn't move start point, e.g. if looking at tall image.
+
+        * xdisp.c (pos_visible_p): Return 0 if non-interactive.
+        Clear last_height before calling line_bottom_y to get real height.
+        Fix calculation of y.

         * s/darwin.h: Removed PTY_ITERATION from here.
