[PATCH 0/4] MR6462: winemac: Use win32u for move/resize window SysCommand.

[Rémi Bernon (＠rbernon)]

It's not completely clear what exactly it was doing differently from win32u, but keeping the captions within the work area is probably fine for win32u, and de-duplicating this code is probably a good thing and makes later changes for DPI-based virtual display settings easier.
