The ICD is intended for use by Khronos' official Vulkan loader, which
typically is shipped as a separate DLL, vulkan-1.dll, although
applications may statically link the loader. The interaction between
an ICD and a loader is well documented[1].

I have provisional patches available on my Github repository[2]. It's
not yet fully complete though, missing the WSI integration. My plan is
to link to winex11.drv and map a HWND to xlib's Display* and Window.
Maybe that's not the best solution, in which case, I'd love to hear
your suggestions.
