I'm posting to ask if the quartz composer plugin comes with safari by default in lion. I'm wondering if I need it. I just got my rMBP and noticed that it was in the plugins folder. The only plugins I remember installing are the googletalkbrowser plugin and the silverlight plugin. Is that quart composer plugin necessary and installed by default? I searched on google for its function but I couldn't find an exact answer and I also couldn't find out if it was installed by default.
