[Freetype] how to use freetype2's cache system for bold, italic and rotation

[wjjdtvout]

Without using cache, I can render embolded characters by functions relating to FT_Outline.

But when I used the cache system, only regular characters are rendered. It seems that the cache system in freetype2 can not cope with bold, italic and rotation.

Can you give me some good ideas about how to use cache in freetype2 ?
