+ truetype: Extend TT_Face->num_locations for broken TTFs.
+
+ * include/freetype/internal/tttypes.h:
+ TT_Face->num_locations are extended from FT_UInt
+ to FT_ULong, to stand with broken huge loca table.
+ Some people insists there are broken TTF including
+ the glyphs over 16-bit limitation, in PRC market.
+ * src/truetype/ttpload.c (tt_face_load_loca):
+ Remove unrequired 16-bit truncation for FT_UInt
+ TT_Face->num_locations.
