Continue to increase the object id even after FcFini()
and detect the overflow. that would be rather easier than
reset the object id with the complicated mutex and atomic
functions.
This situation would be quite unlikely to happen though
Adds FC_SYMBOL.
This affects fonts having a cmap with platform 3 encoding 0.
We now map their glyphs from the PUA area to the Latin1 area.
See thread "Webdings and other MS symbol fonts don't display"
on the mailing list.
Test before/after with:
$ pango-view --markup --text='<span fallback="false">×</span>' --font=Wingdings
Paths starting with '/' don't make sense on W32 as-is,
prepend the installation root directory to them.
This allows the cache to be contained within a particular
fontconfig installation (as long as the default
--with-cache-dir= is overriden at configure time).
Prior to the change of 32ac7c75e8
FcConfigAppFontAddFile() always returned FcTrue no matter what
fonts was added. after that, it always returned FcFalse because
adding a font doesn't add any subdirs with FcFileScanConfig().
so changing that to simply ignore it.
Also fixing it to return FcFalse if non-fonts was added, i.e.
FcFreeTypeQuery() fails.

After the change of d6a5cc665a
we have a lot of code points in FcBlanks. doing the linear search
on the array isn't comfortable anymore.
So re-implementing FcBlanksIsMember() to use the binary search.
Figuring out how much improved after this change depends on
how many fonts proceed with fc-cache say though, it's about 20 times
faster here on testing. which sounds good enough for
improvement.
Assuming that d_name is the last member of struct dirent.
In POSIX, the maximum length of d_name is defined as NAME_MAX
or FILENAME_MAX though, that assumption may be wrong on some
platforms where defines d_name as the flexible array member
and allocate the minimum memory to store d_name.
Patch from Raimund Steger
A while back we removed Apple Roman encoding support. This broke
symbol fonts (Wingdings, etc) because those fonts come with two
cmaps:
1) platform=1,encoding=0, aka Apple Roman, which maps identity,
2) platform=3,encoding=0, aka MS Symbol font
Now, the reason the Apple Roman removal "broke" these fonts is
obvious, and for the better: these fonts were mapping ASCII and
other Latin chars to symbols.
The reason the fonts didn't work anymore, however, is that we were
mishandling the MS symbol-font cmaps. In their modern incarnation
they are like regular non-symbol-font cmap that map PUA codepoints
to symbols. We want to expose those as such. Hence, this change
just removes the special-handling for that.
Now, the reason this confusion happened, if I was to guess, is either
that FreeType docs are wrong saying that FT_ENCODING_MS_SYMBOL is
the "Microsoft Symbol encoding, used to encode mathematical symbols":
http://www.kostis.net/charsets/symbol.htm
or maybe it started that way, but turned into also mapping MS symbol-
font cmaps, which is a completely different thing. At any rate, I
don't know if there are any fonts that use this thing these days, but
the code here didn't seem to produce charset for any font. By now I'm
convinced that this change is the Right Thing to do. The MS Symbol
thing was called AdobeSymbol in our code by the way.
This fixes the much-reported bug that windings, etc are not usable
with recent fontconfig:
https://bugs.freedesktop.org/show_bug.cgi?id=58641
Now I see PUA mappings reported for Wingdings.
This also fixes:
Bug 48947 - Drop the non-Unicode cmap support gradually
https://bugs.freedesktop.org/show_bug.cgi?id=48947
since the AdobeSymbol was the last non-Unicode cmap we were
trying to parse (very incorrectly).
Lots of code around this change can be simplified. I'll push those
out (including removing the table itself) in subsequent changes.
Passing -Werror in the scandir() checks caused Studio cc to report
"Unrecognized option errors", confusing configure into thinking that
scandir() was not available. Use Studio equivalent flags instead.
Leaves -Werror as the default for all other compilers, including
unknown ones, to flag to them that they need to update their flags
as well if -Werror is not correct for them.
