Wrong value for PM_ScrollBarExtent on Windows XP.
Wrong value for PM_ScrollBarExtent on Windows XP.

The NONCLIENTMETRICSW::iPaddedBorderWidth member is supported only on
Windows Vista and above. So when calling the SystemParametersInfo
for SPI_GETNONCLIENTMETRICS on Windows XP, the size for that member
needs to be removed from NONCLIENTMETRICSW::cbSize.
