Subject: Use threadsafe set implementation for hb_language lookups
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8d6183ebc4697a434776cf2aec7857d63a7d881;p=platform%2Fupstream%2FlibHarfBuzzSharp.git

Use threadsafe set implementation for hb_language lookups

Note that the static variable has to be a global static, as gcc
implements local statics differently and that would require linking
to libstdc++, which we don't want.
