Corrected one final case of extracting an extended-drain pFET 

because the opposite type (pwell) is not directly underneath the
gate, but touches it on the plane below.  Because the pwell may
be represented by space tiles on the well plane, it was also
necessary to deal with the space type in the bitmask.
