Any browser implementing compositing for the Core Animation drawing models would return true for this variable in NPN_GetValue. Browsers that returned false would be known not to support it, while browsers returning an error would need to be checked by user agent (for compatibility with browsers that support compositing but have not implemented this new specification). | Any browser implementing compositing for the Core Animation drawing models would return true for this variable in NPN_GetValue.
