         (gs_load): Use printmax_t to print the widest integers possible.
         Check for integer overflow when computing image height and width.

+        * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
+        buffers, return left-to-right.
+        (set_cursor_from_row): Consider candidate row a win if its glyph
+        represents a newline and point is on that newline.  Fixes cursor
+        positioning on the newline at EOL of R2L text within L2R
+        paragraph, and vice versa.
+        (try_cursor_movement): Check continued rows, in addition to
+        continuation rows.  Fixes unwarranted scroll when point enters a
+        continued line of R2L text within an L2R paragraph, or vice versa.
+        (cursor_row_p): Consider the case of point being equal to
+        MATRIX_ROW_END_CHARPOS.  Prevents cursor being stuck when moving
+        from the end of a short line to the beginning of a continued line
+        of R2L text within L2R paragraph.
+        (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
+        composed characters.
+
+        * bidi.c (bidi_check_type): Use xassert.
+        (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
+        members.

+        * xdisp.c (redisplay_window): When computing centering_position,
+        account for the height of the header line.  (Bug#8874)
+
+        * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
+        instead of CHAR_TO_BYTE.  Fixes a crash when a completion
+        candidate is selected by the mouse, and that candidate has a
+        composed character under the mouse.
+
+        * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1.  Fixes pixel
+        coordinates reported by pos-visible-in-window-p for a composed
+        character in column zero.
