/**
 * A visual Node in the Renderer scene graph.
 *
 * @remarks
 * A Node is a basic building block of the Renderer scene graph. It can be a
 * container for other Nodes, or it can be a leaf Node that renders a solid
 * color, gradient, image, or specific texture, using a specific shader.
 *
 * For text rendering Nodes, see {@link ITextNode}.
 *
 * ## INode vs CoreNode
 * CoreNode is the name of the class for a Renderer Node and is only directly
 * used internally by the Renderer. INode describes the public API of a
 * Renderer Node including the ability to be tied to a specific Shader.
 *
 * Users of the Renderer API, should generally interact with INode objects
 * instead of CoreNode objects.
