-// VZ: initial implementation (by JACS) only remembered the last wxPaintDC
-//     created and tried to reuse - this was supposed to take care of a
-//     situation when a derived class OnPaint() calls base class OnPaint()
-//     because in this case ::BeginPaint() shouldn't be called second time.
-//
-//     I'm not sure how useful this is, however we must remember the HWND
-//     associated with the last HDC as well - otherwise we may (and will!) try
-//     to reuse the HDC for another HWND which is a nice recipe for disaster.
-//
-//     So we store a list of windows for which we already have the DC and not
-//     just one single hDC. This seems to work, but I'm really not sure about
-//     the usefullness of the whole idea - IMHO it's much better to not call
-//     base class OnPaint() at all, or, if we really want to allow it, add a
-//     "wxPaintDC *" parameter to wxPaintEvent which should be used if it's
-//     !NULL instead of creating a new DC.
