virtual bool	handles2D () const
	Retrieves whether this post processor should be used in 2D orthographic views, as specified in its constructor.
virtual const std::string &	type () const
	Gets the type of the post processor.
virtual bool	postProcessorEnabled () const
	Is this post processor enabled?
virtual bool	enableEffect (const std::string &effect)
	Enable a particular post processing technique For example, "wateroncamera" has techniques "rainsplash", "oceanspray", and "wavesplash".
