EffectOnBeginUpdate Method

OnBeginUpdate method needs to be implemented by the effect class. The method is called from the BeginUpdate(RenderingContext) method. It can be used to read some data from the RenderingContext (for example CurrentSwapChainImageIndex). It is used with the OnEndUpdate(RenderingContext) method to prepare all the data for the next rendered frame.
