The format '%{[]family,familylang{expr}}' expands expr once for the first
value of family and familylang, then for the second, etc, until both lists
are exhausted.
The '%{=unparse}' format expands to the FcNameUnparse() result on the
pattern. Need to add '%{=verbose}' for FcPatternPrint() output but
need to change that function to output to a string first.
Also added the '%{=fclist}' and '%{=fcmatch}' which format like the
default format of fc-list and fc-match respectively.
The format '%{family|delete( )}' expands to family values with space removed.
The format '%{family|translate( ,-)}' expands to family values with space
replaced by dash. Multiple chars are supported, like tr(1).
The format '%{family|escape(\\ )}' expands to family values with space
escaped using backslash.
The format '%{family|downcase}' for example prints the lowercase of
the family element. Three converters are defined right now:
'downcase', 'basename', and 'dirname'.
The conditional '%{?elt1,elt2,!elt3{expr1}{expr2}}' will evaluate
expr1 if elt1 and elt2 exist in pattern and elt3 doesn't exist, and
expr2 otherwise. The '{expr2}' part is optional.
The filtering, '%{+elt1,elt2,elt3{subexpr}}' will evaluate subexpr
with a pattern only having the listed elements from the surrounding
pattern.
The deletion, '%{-elt1,elt2,elt3{subexpr}}' will evaluate subexpr
with a the surrounding pattern sans the listed elements.
Diego Santa Cruz pointed out that we are using that API wrongly.
The forth argument is a pointer to a pointer. Turns out we don't
need that arugment and it accepts NULL, so just pass that.
Hinting will be done before Embolden in freetype2,
but in such case, Embolden will get wrong result
on some glyph contours after applying hinting.
Actually, hinting should be done after embolden, but we can't
fix it in current freetype2. So as a workaround, just turn off
hinting if we want to do embolden.
For Iraq, we are assuming its the same Arabic orthography used in Iran.
According to Ethnologue, Kurdish is written in Cyrillic in Armenia:

Turkey and Syria need more research.
The previous version used the Devanagari script. But in both Pakistan and
India, Sindhi is generally written in Arabic. The Devanagari data could
prove to be useful, if we decide on how we should name such files (see
bug #17208 and bug #19869).
To only work on writable charsets. Also, return a bool indicating whether
the merge changed the charset.
Also changes the implementation of FcCharSetMerge and FcCharSetIsSubset
