Image cut when using some font

[wanmeihuali]

I think the reason is that PIL's textsize() function does not consider the offset of the font.
python-pillow/Pillow#644
I don't know it is a bug or feature for PIL, But you can fix this by just adding the offset the w and h in _draw_character() function.

I rechecked this problem and found that they have fixed it in one of the pillow version. So this problem can be fixed by updating pillow.
