    Serial devices send both pen and touch data through the same logical
    port. Since we scaled touch to pen maximum, we use pen resolution
    for touch as well here.
    
    This is under the assumption that pen and touch share the same physical
    surface. In the case when a small physical dimensional difference occurs
    between pen and touch, we assume the tolerance for touch point precision
    is higher than pen and the difference is within touch point tolerance.
    
    A per-MT tool based resolution mechanism should be introduced if the
    above assumption does not hold true for the pen and touch devices any
    more.
