The WebGLRenderer.deleteFramebuffer method has been updated so it now tests for the exitennce of a COLOR and DEPTH_STENCIL attachments, and if found, removes the bindings and deletes the stencil buffer. The code that previously deelted the RENDERERBUFFER_BINDING has also been removed to avoid side-effects.
