[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.
