* Add runtime type safety to uniform bindings (and maybe compile time)
* Inject layout set/bindings into shader source so they don't need to be defined in-shader. Specify set / binding indices in resource providers?
* Pull as much logic as possible from wgpu_renderer into a "render orchestrator" struct/trait
* Separate original/uncompiled/no_defs PipelineDescriptor from compiled PipelineDescriptor conceptually
* Try to make Renderer a resource + system
* Docs
* Add doc comments to code
* Add tutorials
