[Bug 42820] Multiple games (The Witness, Just Cause 2) require D3D11 multisample textures

--- Comment #9 from Pekka Helenius  ---
I configured the patch for Wine 2.18 Staging. I did multiple test runs with and
without the patch for Witcher 3. I have not played the game so much, just
actually the initial room and the first staircase. I can't tell any
differences. I did testing with ROTTR, too. No major differences either.

Disclaimer: I don't know whether the current form of the patch code applies
good enough to current Wine Staging version due to multiple D3D11 commits after
the May when the patch was initially published. Wine devs have better
understanding of this topic.

I may add the re-adapted patch & debugging stuff later, if needed.
