*Summary*
--------
+virtual void PrePaint()
*Description*
-------------
CWS aw033 adds a virtual PrePaint handler to Window. PrePaint will be
called immediately before a paint and will allow to invalidate some
additional regions that will be updated in the following paint.
Caveat: if the resulting invalidate region is empty after PrePaint or
is completely invisible due to other windows occluding the area, Paint
will not actually be called. So there may be more PrePaint calls than
Paint calls.
