Subject: Reference patterns in FcCacheCopySet.
X-Git-Tag: 2.4.0~13
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=8d779ce4b3cdac796e20ca568654c0ef1c576809;p=fontconfig.git

Reference patterns in FcCacheCopySet.

As patterns are put into the font set copy, mark them as referenced so the
cache stays around while the font set is in use.
