Corrected the terminal resistance values for the xhigh_po (2000
ohms/sq. nominal) resistor, which were set to some old value
left over from cut-and-paste and not updated like the high_po
(320 ohms/sq. nominal) resistor. This error causes major
discrepancies for the calculated device value when W is short.
Note that this only affects the displayed value of the resistor
in the device generator; the device simulates according to the
correct width and length.
