I wasn't asking about multiple renderers on one view, but rather 
multiple views on one renderer.  I don't actually want to do that.  
I've been thinking about possible solutions to bug 902975, "Use shared 
texture namespace".  If I could assume that there is a one to one 
correspondence between views and renderer, it would make the problem a 
little simpler.
