  [truetype] Upstream the hdmx binary search.
  
  * src/truetype/ttobjs.h (TT_SizeRec): Add `widthp` for the hdmx
  widths.
  * src/truetype/ttobjs.c (tt_size_reset): Initialize `widthp` even
  though it might never be used by the interpreter.
  * src/truetype/ttgload.c (tt_loader_init): Avoid repeated searches
  in the hdmx table.
