I remember Wine being extremely interwined with XLib not just for the OpenGL rendering backend but also for the windowing and widget/UI rendering interfaces. Is this port running natively without using an X server / emulator?

No? The article extensively discusses the use of XOrg. With that said, the Wine graphics abstractions are a lot better now and there are many working backends (winex11, winemac, winewayland, winehaiku, etc.)
