[poppler] Wrong hinting

[mpsuzuki at hiroshima-u.ac.jp]

Hi,

Oops, so many posts during I was checking the embedded
font by FreeType2... Now I think this issue is not by
poppler but by FreeType2.

The font extracted from sample PDF is:

	http://ompldr.org/vN2YyaQ/cedric-font.ttf

If I show the font by ftview (a small sample program
of FreeType2), the rasterization result for the case
hint=on && antialias=on is worse than others.
The comparison is:

This is by the latest FreeType2. I will discuss other
FreeType2 maintainer what I can do for this issue.

Regards,
