	OpenGl_FrameBuffer (GLint theTextureFormat=GL_RGBA8)
virtual	~OpenGl_FrameBuffer ()
GLsizei	GetSizeX () const
	Texture width.
GLsizei	GetSizeY () const
	Texture height.
GLsizei	GetVPSizeX () const
	Viewport width.
GLsizei	GetVPSizeY () const
	Viewport height.
Standard_Boolean	IsValid () const
	Returns true if current object was initialized.
Standard_Boolean	Init (GLsizei theViewportSizeX, GLsizei theViewportSizeY, GLboolean toForcePowerOfTwo=GL_FALSE)
	Notice! Obsolete hardware (GeForce FX etc) doesn't support rectangular textures! There are 3 possible results if you are trying to create non power-of-two FBO on these cards: 1) FBO creation will fail, current implementation will try to generate compatible FBO; 2) FBO rendering will be done in software mode (ForceWare 'hack'); 3) FBO rendering will be incorrect (some obsolete Catalyst drivers).
void	Release ()
	Release GL objects.
void	SetupViewport ()
	Setup viewport to render into FBO.
void	ChangeViewport (const GLsizei theVPSizeX, const GLsizei theVPSizeY)
	Override viewport settings.
void	BindBuffer ()
	Bind frame buffer (to render into the texture).
void	UnbindBuffer ()
	Unbind frame buffer.
void	BindTexture ()
	Bind the texture.
void	UnbindTexture ()
	Unbind the texture.
Static Public Attributes
static const GLuint	NO_TEXTURE = 0
	Helpful constants.
static const GLuint	NO_FRAMEBUFFER = 0
static const GLuint	NO_RENDERBUFFER = 0
