Chris Lamb f098adac54 Ensure cache checksums are deterministic
Whilst working on the Reproducible Builds[0] effort, we noticed that
fontconfig generates unreproducible cache files.

This is due to fc-cache uses the modification timestamps of each
directory in the "checksum" and "checksum_nano" members of the _FcCache
struct. This is so that it can identify which cache files are valid
and/or require regeneration.

This patch changes the behaviour of the checksum calculations to prefer
the value of the SOURCE_DATE_EPOCH[1] environment variable over the
directory's own mtime. This variable can then be exported by build
systems to ensure reproducible output.

If SOURCE_DATE_EPOCH is not set or is newer than the mtime of the
directory, the existing behaviour is unchanged.

This work was sponsored by Tails[2].

Akira TAGOH 10a57edd07 Add one more debugging option to see transformation on font-matching
just setting FC_MATCH=3 shows a lot of information and hard to keep on track for informamtion
which is really necessary to see. to use this more effectively, added FC_DBG_MATCH_FILTER to
see for what one really want to see. it takes a comma-separated-list of object names.
If you want to see family name only, try like this:

FC_DBG_MATCH_FILTER=family FC_DEBUG=4096 fc-match

debugging output will be filtered out and see family only in the result.

Akira TAGOH 20191810d1 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.

follows that would correspond to one available for Cairo in bug 10301.

Keith Packard c2c6976d1a Add FcMatchScan to resolve Delicious font matching issues (bug #6769)
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.
