So, I'm having a lot of the same debates with myself right now as well and this is a great synopsis. I guess my one big concern is, can we...

Okay, here's a structure I came up with and briefly explored in my head but haven't really thought all the way through: base the renderer design/structure somewhat on specs' design,...
