Description Ron MacNeil 2010-01-16 09:10:00 UTC 
All subpixel LCD filtering support was removed from cairo in late 2008...

http://cgit.freedesktop.org/cairo/commit/?id=5d887ad5dca5af0f8216830d1b04d08a5aba9bee

..and has never returned.

Fix: 1) Drop attached patch file in /usr/ports/graphics/cairo/files, rebuild,
and reinstall

2) Make sure your print/freetype2 was built WITH_LCD_FILTERING

3) Set your 'lcdfilter' preference as usual in fonts.conf, .Xdefaults,
your GUI config tool, etc.

4) No more pretty rainbows :(

Patch attached with submission follows:
How-To-Repeat: View subpixel antialiased text generated by unpatched cairo-1.8.8 (in
gtk or firefox, for example) and enjoy the pretty rainbows.

This patch looks big. It's going to be hard to keep it maintains in future if 
the cairo changes too much. If they remove then we follow it by use their 
own default tarball.

This patch still works with cairo-1.8.10_1,1.
Comment 4 swell.k 2010-11-10 19:31:20 UTC 
Let's just wait for cairo 1.10 update which includes it.
