+ * This technique will work fine for all windows whose parents
+ * have the WS_CLIPCHILDREN style. When the parents have that style,

+ * 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
