[Devel] CJK font autohinting & gamma adjustment patch

[Funda Wang]

Hello,

I've noticed that freetype currently cannot apply autohinting feature to
CJK fonts correctly. So, contribution from Chinese programmer might be
needed.

A Chinese programmer whose nickname is Firefly made his own patch to
freetype2.1.4. The patch is divided into three parts:
1. CJK fonts autohinter
// partly from the code written by akito, http://www.kde.gr.jp/~akito/xft/
http://firefly.idv.tw/setfont-xft/patches/freetype/freetype-2.1.4-autohint-cjkfonts-20030511.patch
2. Automatic correction missing Chinese map, plus bytecode enabled
http://firefly.idv.tw/setfont-xft/patches/freetype/freetype-2.1.4-misscmap-enablebytecode-20030410.patch
3. More readable Chinese characters by adjusting rendering gamma

If it is possible, please check them out and merge them in the future.
Because the three patches are independent respectively, so there is no
problem just applying one or two of them.
