Yeah, nsCSSParser can’t be used from other threads, although it might not be too much work to make it threadsafe for the things that 2D canvas contexts need it for. In fact that might be less work than duplicating <color> and <‘font’> parsing. -- Cameron McCormack ≝ http://mcc.id.au/ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
