    integer overflow in XineramaQueryScreens() [CVE-2013-1985]
    
    If the reported number of screens is too large, the calculations to
    allocate memory for them may overflow, leaving us writing beyond the
    bounds of the allocation.

    Use _XEatDataWords to avoid overflow of _XEatData calculations
    
    rep.length is a CARD32, so rep.length << 2 could overflow in 32-bit builds
