* Paint is now the non-virtual entry point to OnPaint to support required pre/post functionality. Widgets override OnPaint as usual, but calls to tell a widget to paint should be "Paint" not "OnPaint".
* ArrangeChildren -> OnArrangeChildren. ArrangeChildren is now the non-virtual entry point for the same reason as Paint/OnPain.
* OnPaint and OnArrageChildren are now private so they are not accidentally called.
* Added Stats for Paint time and ArrangeChildren time.
