"Shares" as in uses system RAM for the GPU, like an integrated Intel GPU?  Or something else?

I'm not aware of any way to query this from the Mac APIs.  I could just return true for Intel GPUs and false for everything else.  Or I could just leave it as a FIXME, since there's no current or anticipated client that will ever query it. ;)

OK, I can try to extract it from that string.  I gather that nothing past major.minor is standardized in that string, in general, but it may be more predictable on OS X.

Thanks,
