* Color source implementation for a single level of instancing. I don't like it. I don't believe it's the right way to go
* Forgot this
* Rewritten the way prxy color sources are handled. Nesting instances now works for the most part
* Handled block-block situation from instance nesting
* Added sum comments for color proxy source implementation
* Disabled tonemaping for line materials
