Using hinting=true, hintstyle=hintfull and antialias=true
is a good default for most fonts.
Match on "pattern" for the default, not on "font" to make
it easier to override the default using FcPatternDel()
and FcPatternAdd...() (see bugzilla #104365).

<!--
Set autohinter=true as the default, then add exceptions for certain fonts.
Match on "font" here, not on "pattern" because of bug #118131 comment #93.
(If an autohint value is set in pattern, OpenOffice 2.1 will use that even
if there are fontconfig rules matching on "font" which should override it
again). This doesn't cause any problems for Cairo/Gnome (see bug #104365)
because Cairo/Gnome don't try to change the autohint value anyway.

TrueType Fonts which have high quality byte code interpreter
instructions can look very good in even in small sizes when using
the byte code interpreter (autohint=false). This is true
both with and without anti-aliasing.
In black and white (antialias=false) the results when rendering
with the byte code interpreter may even look as good as high quality
bitmap fonts.
On the other hand, some low quality TrueType Fonts do not have
byte code interpreter instructions at all or only very bad byte
code and may look better when the autohinter is used.
(See "FreeSans" for example, it looks better with the
autohinter which is especially obvious if anti-aliasing is off).

Switch off the autohinter for TrueType fonts in order
to use the byte code interpreter.

<!--
Switch on the autohinter for a few TrueType fonts which
have no byte code or very bad byte code and look better
with the autohinter:
But see also bug #215602 for many fonts the autohinter
seriously distorts the metrics so badly that
even the digits which should be monospaced are not
monospaced at all anymore.
Because of this problem, better don't switch on
the autohinter for
Sazanami
IPA
DejaVu Sans Light
DejaVu Sans Condensed
DejaVu Serif Condensed
FreeSans
FreeSerif
FreeMono
and other fonts with similar problems until this is solved
in the autohinter.

The following rule sets up black and white rendering with
the byte code interpreter for a small list of fonts which
are known to have good byte code and give bitmap quality
results at small sizes.
The pixelsize limit is set to '0' though, which effectively
disables this rule by default because most users don't like
that bitmap look and feel.
If you like a bitmap look and feel of your desktop,
copy this rule into your ~/.fonts.conf file and replace the '0'
with non-zero pixelsize limit. Using '18' as the pixelsize
limit is a good choice if you have the fonts in this list installed
and like a bitmap look and feel.

Some CJK fonts require the byte code interpreter to be rendered correctly.
These are composite fonts which store components and composing information
and compose the glyphs on the fly using the hinting instructions.
For all such fonts we switch off the autohinter here.
When "autohint" is set to "false", the byte code interpreter will
be used if it has been enabled at all when compiling freetype2.
The Chinese fonts "MingLiu" and "PMingLiU" used to belong to the fonts
which absolutely require the byte code interpreter to be rendered
correctly.
But apparently the new versions of "MingLiU" and "PMingLiU" from Windows
Vista are rendered correctly without the byte code interpreter.

Hinting for CJK fonts in freetype doesn't yet work as well as for Latin fonts.
Recently the autohinter in in freetype has been improved for CJK fonts
a lot but it is still not perfect. Therefore one might want to switch
off the autohinter for CJK fonts.
This can be achieved by using the following rule:

<test name="lang" compare="contains">
<string>ja</string>
<string>zh</string>
<string>ko</string>

for some Bengali fonts (e.g. "Mukti Narrow"), the autohinter works well
with the patch from http://www.kde.gr.jp/~akito/patch/freetype2/2.1.7
applied. But for "Likhan" it still doesn't work that well
(look how the "matra" lines at the top line up). Therefore, switch
off the autohinter for the "Likhan" font:
