I decided to make queues explicit, to simplify handling queue ownership
transfers in the renderer code. The framegraph + pass code has explicit knowledge
about resource ownership, so it makes sense to handle it there.
- Manage pools
- Allocate command buffers
- Submit command buffers
- The renderer backend is now its own library, loaded at runtime.
- Removed GLFW dependency, instead use win32 directly.
- Broke linux window creation, because it's not implemented yet.
- Maybe use GLFW for linux?
