* This technique will work fine for all windows whose parents

* However, when the parent doesn't have that style, Windows relies
* on a "painter's algorithm" to display the contents of the windows.
* That is, windows are painted from back to front. This includes the
* non-client area.
*
* This method looks at the current state of a window to determine
* if the sending of the WM_NCPAINT message should be delayed until
* the BeginPaint call.
*
* PARAMS:
* wndPtr - A Locked window pointer to the window we're
* examining.
* uncFlags - This is the flag passed to the WIN_UpdateNCRgn
* function. This is a shortcut for the cases when
* we already know when to avoid scanning all the
* parents of a window. If you already know that this
* window's NCPAINT should be delayed, set the
