[PATCH v3 0/7] MR5747: win32u: Introduce a wrapper to flush window surfaces.

[Rémi Bernon]

--
  v3: win32u: Use a helper to flush window surface, factor locking and bounds reset.
      wineandroid: Hold the lock while reading window surface bits.
      winemac: Get rid of unnecessary blit_data / drawn surface members.
      win32u: Move window surface bounds to the window_surface base struct.
      win32u: Use helpers to lock/unlock window surfaces.
      win32u: Move the window surface mutex to the surface header.
      win32u: Introduce a new window_surface_init helper.

[Rémi Bernon]

I've updated the MR with a dedicated commit for the `wineandroid` behavior change, to make it more obvious, in case it breaks anything.

> If I understand correctly, the perform triggers some ioctl on a dedicated thread? If we need the flush to be done asynchronously, we could also do that the same way as winemac is doing, notifying the drawing thread asynchronously, then, taking the surface lock and reading the data from that thread.

I think it's in the right ballpark. Although it's something to worry if current MR proves problematic
