patches for libXft and cairo to improve font rendering

[Yuri Pankov]

Hi.

There are patches for libXft and cairo, which seem to heavily improve
truetype font rendering (at least on my LCD monitor), at
http://turnerdavid.neuf.fr/freetype/patches/font-patches.html

Is there any chance that they could be added to libXft and cairo ports
(WITH_LCD_RENDERING_PATCH knob maybe)? I'm asking cause author of these
patches is unsure about licensing (cleartype patents are mentioned).

And also, recent libXft doesn't compile with cjk patch (WITH_CJK knob
defined) on recent -CURRENT/amd64:
