Enable the Core Animation NPAPI drawing mode on 10.6 (except for QuickTime)
Enable the Core Animation NPAPI drawing mode on 10.6 (except for QuickTime)

Allows plugins other than QuickTime (see http://crbug.com/38336) to negotiate the Core Animation drawing model.

Note that for the moment, our wmode hack will prevent Flash from trying to use Core Animation; that will be removed later.

BUG=32012
TEST=On 10.6: Unity3D should not use any renderer CPU on most sites, and should now have good performance; QuickTime and Flash10.1 should be unchanged for now. On 10.5: Everything should be unchanged.
