+// Purpose: Has init functions for all the standard render targets used by most games.
+//			Mods who wish to make their own render targets can inherit from this class
+//			and in the 'InitClientRenderTargets' interface called by the engine, set up
+//			their own render targets as well as calling the init functions for various
+//			common render targets provided by this class.
+//
+//			Note: Unless the client defines a singleton interface by inheriting from
+//			this class and exposing the singleton instance, these init and shutdown
+//			functions WILL NOT be called by the engine.
