+
+        Reduce new/delete operations by storing the maximum capacity of the glyph
+        array and use that value in subsequent HB_ShapeItem calls. (Note that a
+        call to HB_ShapeItem may reduce the value of m_item.num_glyphs below the
+        capacity.)
+
+        Also be consistent with zero'ing the glyph arrays before calling 
+        HB_ShapeItem.
+
+        There is no functionality changes so no new tests are added.
