Default Re: NVidia and XRandR 1.2

This is similar to the X driver's TwinViewXineramaInfo option.
Nope no confusion, I am fully aware of that. My test today was specifically to test if the new XRandR 1.2's internal "fakerama" worked with the NVidia drivers. I disabled `Option "Xinerama"` in my "Server_Layout" section in xorg.conf before doing the tests. The point is that because the traditional Xinerama option in xorg.conf disables XRandR you can't use a composite window manager, with the new 1.2 specification handling Xinerama internally, there will be no need to use the `Option "Xinerama"` setting in xorg.conf and therefore XRandR won't be disabled and the user will be able to run a composite window manager and still be able to use a Xinerama type setup by allowing XRandR 1.2 to handle it for them.
