Updated more obsolete pages; they all now point to the Wiki

The main idea is to create new -"render-to-texture" subclasses of Canvas3D and View that would render -into a texture that could then be used in a scene graph to render into -an ordinary on-screen (or off-screen) Canvas3D. We will either need to -create special "rendered" subclasses of Texture (e.g., -RenderedTexture2D), or add a mode flag to the existing texture classes. -The former is cleaner from an API point of view, but the latter is more -flexible (e.g., it would allow some mipmap levels of a Texture or faces -of a TextureCubeMap to be generated by rendering and others to be -specified via an image).<br> +<h2>Obsolete Page</h2> +<p>This page is obsolete.

Violating this will lead to undefined -results. We may want to consider relaxing this restriction to allow for -cascading render-to-texture operations. If we do relax this, we may -need to provide a way for the application to specify an ordering of -TextureViews (determining the dependency graph would be difficult).<br> - </li> - <li>To make it easier for an app to comply with the above, we will -add a new feature to View: a boolean -attribute indicating whether to render <strong><em>only</em></strong> -to nodes under a ViewSpecificGroup.
