Render Graphs 📈

[AntarticCoder]

This issue is a suggestion for rework of the renderer. At the moment we are using raw vulkan primitives to render, which is fine at the moment, but more complex scenes will not scale up nicely. The solution is a render graph, which will allow for better synchronization. This issue is to be used to collect info on render graphs, and how I could implement render graphs.

A realization I've come to is that it would be better finish implementing texturing, and some other basic features before moving on to render graphs. This is because render graphs are highly effective only when you have texture, so that's something I'll need to work out.
