When a cache contains no fonts, it will be unloaded immediately.
Previously the certain alias and UUID entries will be purged at that time though,
this doesn't work when the targeted directory has sub-directories.
To avoid the unnecessary cache creation with the md5-based naming, try to keep them
as far as possible.
Although this way seems not perfectly working if the first directory to look up is like that
Reject caches when FcPattern isn't a constant.
This is usually unlikely to happen but reported.
I've decided to add more validation since this isn't reproducible
and easy to have a workaround rather than investigating 'why'.

Trying to address what these configuration files really do.
This change allows to see the short description that mention
the purpose of the content in the config file and obtain
them through API.
This change also encourage one who want to make some UI for
the user-specific configuration management. it is the main
purpose of this change for me though.
Aside from that, I've also made programs translatable. so
we see more dependencies on the build time for gettext,
and itstool to generate PO from xml.
VotoSerifGX has over 500 named instances, which means it also has over a thousand
name table entries. So we were looking for names for over 500 pattern, looking for
some thirty different name-ids, and using linear search across the 1000 entries!
Makes scanning VotoSerifGX three times faster. The rest is probably the lang
matching, which can also be shared across named-instances. Upcoming.
This reverts commit 57764e3a36449da25bb829c34cb08c54e9e5de90.
For regular font pattern we don't look into fvar, so it doesn't make sense to
get non-variation from it either.
Has two distinctions from FcCompareRange():
1. As best value, it returns query pattern size, even if it's out of font range,
2. Implements semi-closed interval, as that's what OS/2 v5 table defines
If font claims to support range [100,900], and request is for [250], then
return [250] in "rendered" pattern. Previously was returning [100,900].
This is desirable for varfonts weight and width, but probably not for size.
Will roll back size to return request size always, for non-empty ranges.
If "instance-number" part of face id is set to 0x8000, return a pattern
for variable font as a whole. This might have a range for weight, width,
and size.
If no variation is found, NULL is returned.
Not hooked up to FcQueryFaceAll() yet. For now, can be triggered using
fc-query -i 0x80000000
There's nothing assymetrical about how we match them. Previously we "considered"
them half-open because the OS/2 spec had usLowerOpticalPointSize as inclusive
and usUpperOpticalPointSize as exclusive. But we do not respect that.
Note that the parsing code accepts both anyway, because of the way our sscanf()
usage is written...
