Seems like the following will need changes:

        ProcRRSelectInput

                Must send CRTC/OUTPUT events for slave outputs too

        TellChanged

                This one has some changes, but it doesn't send CRTC or
                OUTPUT events for output slave screens.

        RRFirstOutput

                There may only be slave outputs running, so it needs to
                look there as well

        RRModesForScreen

        ProcRRSetScreenSize

                Screen size needs to cover the slave outputs as well

        RRXineramaScreenCount
        ProcRRXineramaQueryScreens

                Xinerama needs to report all of the crtcs, not just the
                master ones.
