The following functions were problematic: const SkGlyph& getUnicharMetrics(SkUnichar, const SkMatrix*); const SkGlyph& getGlyphMetrics(uint16_t, const SkMatrix*); const void* findImage(const SkGlyph&, const SkMatrix*); Replacing them with calls through SkGlyphCache solved a nasty crash bug, so they have all been deprecated.
