override void	OnPaintBackground (PaintEventArgs pevent)
	Ignores WinForms paint-background messages. The default implementation would clear the control to the current background color, causing flickering when our OnPaint implementation then immediately draws some other color over the top using the XNA Framework GraphicsDevice. More...
