Clear the window framebuffer and the fragmap framebuffer.

Create an affine transformation that locates the camera at `position`, s.t. it looks at `target`. :param position: The 3D position of the cam

Release all OpenGL resources used by this node and any of its children. Subclasses that instantiate OpenGL objects should implement t
