[PATCH 0/1] MR6805: winewayland: Fix surface scaling with HiDPI compositor.

[Rémi Bernon]

The surface scale is there to match between the Wine DPI and the
compositor scaling, not to implement Wine DPI scaling, ie: when
compositor scaling is set to 200% and Wine DPI is also set to 192,
windows are shown at 1:1 scale, instead of being upscaled twice.
