[PATCH 0/8] MR6649: Draft: winex11: Replace foreign windows with a driver-only host window tracking.

[Rémi Bernon (＠rbernon)]

Making all the windows handled by the driver to be either GL/VK client surfaces, or top-level windows. This avoids leaking host windows into the Win32 space, and makes it possible to get rid of some remaining NtUserMapWindowPoints in `map_event_coords` for mouse input.
