The OT spec says:
"When building a Unicode font for Windows, the platform ID should be 3 and the
encoding ID should be 1. When building a symbol font for Windows, the platform
ID should be 3 and the encoding ID should be 0."
We were ignoring the SYMBOL_CS entry before. It's UTF-16/UCS-2 like the
UNICODE_CS.
Also, always use UTF-16BE instead of UCS-2BE. The conversion was doing
UTF-16BE anyway.
Bitmap-only TrueType fonts without a glyf table will not load a glyph when
FT_LOAD_NO_SCALE is set. Work around this by identifying TrueType fonts that have no
glyphs and select a single strike to measure the glyph map with.
Glyph names (now used only for dingbats) were using many relocations,
causing startup latency plus per-process memory usage. Replace pointers with
table indices, shrinking table size and elimninating relocations.
The old policy of eliding fullname entries which matched FC_FAMILY or
FC_FAMILY + FC_STYLE meant that applications could not know what the
font foundry set as the fullname of the font. Hiding information is not
helpful.
Recent versions of FreeType do not correctly deal with glyph name buffers
that are too small; work around this by declaring a buffer that can hold any
PS name (127 bytes).
Instead of accepting whatever order names appear in the font file,
use an explicit ordering for both platform and nameid.
Platforms are high precedence than nameids.
The platform order is:
microsoft, apple unicode, macintosh, (other)
The family nameid order is:
preferred family, font family
The fullname nameid order is:
mac full name, full name
The style nameid order is
preferred subfamily, font subfamily
This will change the names visible to users in various application UIs, but
should not change how existing font names are matched as all names remain
present in the resulting database. The hope is that family names will, in
general, be less ambiguous. Testing here shows that commercial fonts
have longer names now while DejaVu has a shorter family name, and moves more
of the font description to the style name.
The existing loop for discovering which characters map to glyphs is ugly and
inefficient. The replacement is functionally identical, but far cleaner and
faster.
Using a simple shell script that processes the public headers, two header
files are constructed that map public symbols to hidden internal aliases
avoiding the assocated PLT entry for referring to a public symbol.
A few mistakes in the FcPrivate/FcPublic annotations were also discovered
through this process
The Delicious family includes one named Delicious Heavy, a bold variant
which is unfortunately marked as having normal weight. Because the family
name is 'Delicious', fontconfig accidentally selects this font instead of
the normal weight variant. The fix here rewrites the scanned data by running
the scanned pattern through a new substitution sequence tagged with
<match target=scan>; a sample for the Delicious family is included to
demonstrate how it works (and fix Delicious at the same time).
Also added was a new match predicate -- the 'decorative' predicate which is
automatically detected in fonts by searching style names for key decorative
phrases like SmallCaps, Shadow, Embosed and Antiqua. Suggestions for
additional decorative key words are welcome. This should have little effect
on font matching except when two fonts share the same characteristics except
for this value.
Many Japanese fonts incorrectly include names tagged as Roman encoding and
English language which are actually Japanese names in the SJIS encoding.
Guess that names with a large number of high bits set are SJIS encoded
Japanese names rather than English names.
permitting cache files to be stored in font dirs. Bump cache magic.
Don't include /fonts.cache-2 in cache hash construction.

Make fontconfig compile under MinGW:
1) remove unneeded #includes;
2) make use of mmap and sysconf conditional;
3) replace rand_r by srand/rand if needed;
4) use chsize instead of ftruncate; and
5) update libtool exports file
