Public Member Functions
virtual	~Ogre2RenderWindow ()
	Destructor.
virtual void	Destroy () override

virtual Ogre::TextureGpu *	RenderTarget () const override
	Get a pointer to the ogre render target containing the results of the render.
Public Member Functions inherited from BaseRenderWindow< Ogre2RenderTarget >

virtual	~BaseRenderWindow ()
virtual double	DevicePixelRatio () const
	Get the device to pixel ratio.

	Destructor.
Public Member Functions inherited from RenderTarget
virtual	~RenderTarget ()
	Destructor.
virtual void	PreRender ()=0

Public Member Functions inherited from Object
virtual	~Object ()
	Destructor.
virtual unsigned int	Id () const =0
	Get the object ID. This ID will be unique across all objects inside a given scene, but necessarily true for objects across different scenes.

virtual void	SetCamera (Ogre::Camera *_camera)
	Set the ogre camera to use for this render target.
