    Use RRScreenSetSizeRange in 1.0 compat. Check RRGetInfo for error.
    
    The RRScreenSizeSetRange function is used externally for 1.2 API drivers,
    but can also be used in the 1.0 compatibility code. This also ensures that
    the right changed bits are set so that clients are correctly notified when
    the range changes.
    
    RRGetInfo can return an error, use that to return BadAlloc to clients
    instead of blindly going on with various requests.
    (cherry picked from f05dd384d38c76dd9662933a03625dfef5b1c81f commit)
