title: Can you use raw WebGL Textures with three.js
body: <p>I have a fairly complicated architecture where I am doing most of my stuff in Three.JS but I also have a special renderer that renders directly to a raw WebGL texture.  Is it possible to use this WebGL texture in a three.js "Texture"?  It looks like the Three.JS texture class is just a container for an image or video or canvas, and somewhere deep in the guts of three.js it will upload that to a real webgl texture.  How can I just have Three.js render my WebGL texture onto a mesh?</p>
