Not a lot to show in this image, but as you can see I did get the mutliple viewport rendering up. I decided to go on the cheap somewhat in architecting it. It really only allows different views of the same scene, not full blown different renderings. If I even decide to do split screen (which I don't think I will) that will be sufficient. With the multi-threaded rendering, adding multiple rending list for each viewport would require a fairly big rewrite. I just need rendering viewports for the editor, and I can get away with this.
