When you receive the WM_NCPAINT message the wParam argument is a handle to
the region to be painted.  All non-client paint messages give you a
rectangular region and a call to GetRegionData can be used to find the
rectangular coordinates of the area to be painted.  The part of the
nonclient area to not be painted is the part of the area for which you have
not received a message requesting that it be painted.
