Looks like it didn't get much love :D

Another possible solution (wine agnostic) would be to use an X11 server
on top of the current X11 server, since the major concern for me is
fullscreen apps.

The original question though was something like "how many interactions
in terms of resolution does the X11 wine Drv have?" to get an idea of
how much effort would be to implement scaling.
