"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.
