    Fix a SIGSEGV on FcPatternGet* with NULL pattern

    Fix crash with FcConfigSetCurrent(NULL)

    Do not copy FC_*LANG_OBJECT even if it's not available on the pattern
    those objects are linked to the corresponding string objects.
    this may causes inconsistency that those objects has more values
    than them.

    Bug 59456 - Adding a --sysroot like option to fc-cache
    Add an ability to set the system root to generate the caches.
    In order to do this, new APIs, FcConfigGetSysRoot() and
    FcConfigSetSysRoot() is available.

    Fix a memory leak

    Bug 60748 - broken conf.d/10-autohint.conf and conf.d/10-unhinted.conf
    Move the target of recipes to the "pattern" from the "font".
    This is to ensure the targeted objects is updated by them
    prior to FcDefaultSubstitute() so that it can adds the default
    values properly.

    Accept digits as part of OpenType script tags
    They've been used since 2005.

    Add Culmus foundry to the vendor list
    Maps fonts produced by the Culmus project
    <http://culmus.sourceforge.net>
    to the XLFD foundry name culmus.
    For TrueType fonts, maps the vendor code CLM from the TrueType vendor
    id field.
    For Type1 fonts, which use heuristics to guess mappings to XLFD
    foundries from
    words in the copyright notice, add the names of the main contributors
    to
    the Culmus product to recognize the fonts under their copyright.

    Use LOG_COMPILER and AM_TESTS_ENVIRONMENT

    Bump the cache version to 4

    Update _FcMatchers definition logic
    to make it easier to maintain. also added FC_HASH_OBJECT to be matched
    in the pattern, prior to FC_FILE_OBJECT.

    Bug 60312 - DIST_SUBDIRS should never appear in a conditional
    As it is documented like this:
    If SUBDIRS is defined conditionally using Automake conditionals,
    Automake will define DIST_SUBDIRS automatically from the possible
    values of SUBDIRS in all conditions.
    So we don't need to re-define DIST_SUBDIRS in Makefile.am unless
    we use AC_SUBST to define SUBDIRS.
    Patch from Quentin Glidic

    Bug 50733 - Add font-file hash?
    Add "hash" object which contains SHA256 hash value (so far) computed
    from the font file.

    Use AM_MISSING_PROG instead of hardcoding missing

    Revert "test: Use SH_LOG_COMPILER and AM_TESTS_ENVIRONMENT"
    This reverts commit 2146b0307a3476892723104481f27f8484451c52.
    That change introduces incompatibility and seems not working with
    older releases of automake, including automake 1.12.2.

    Bug 23757 - Add mode="delete" to <edit>
    Add two edit mode, "delete" and "delete_all".
    what values are being deleted depends on <test> as documented.
    if the target object is same to what is tested, matching value there
    will be deleted. otherwise all of values in the object will be
    deleted.
    so this would means both edit mode will not take any expressions.
    e.g.
    Given that the testing is always true here, the following rules:
      <match>
        <test name="foo" compare="eq">
          <string>bar</string>
        </test>
        <edit name="foo" mode="delete"/>
      </match>
    will removes "bar" string from "foo" object. and:
      <match>
        <test name="foo" compare="eq">
          <string>foo</string>
        </test>
        <edit name="bar" mode="delete"/>
      </match>
    will removes all of values in "bar" object.

    build: Only use PKG_INSTALLDIR if available
    It's only in pkg-config 0.27 or newer, but 0.25 at least is still
    fairly widespread.

    Use the PKG_INSTALLDIR macro.

    Bug 59385 - Do the right thing for intermixed edit and test elements
    This changes allows to have multiple mathcing rules in one <match>
    block
    in the same order.

    Reported at

    just warn at the runtime instead of the compile time. it somewhat
    works
    on even MinGW since FcMakeTempfile() isn't used on Win32 so far.
