Compatibility tool for Steam Play based on Wine and additional components

It includes a modified distribution of Wine, called Proton, to provide compatibility with Windows game titles. Here are some of the improvements it brings to the table:
- Windows games with no Linux version currently available can now be installed and run directly from the Linux Steam client, complete with native Steamworks and OpenVR support.
- DirectX 11 and 12 implementations are now based on Vulkan, resulting in improved game compatibility and reduced performance impact.
- Fullscreen support has been improved: fullscreen games will be seamlessly stretched to the desired display without interfering with the native monitor resolution or requiring the use of a virtual desktop.
- Improved game controller support: games will automatically recognize all controllers supported by Steam. Expect more out-of-the-box controller compatibility than even the original version of the game.
- Performance for multi-threaded games has been greatly improved compared to vanilla Wine.
Modifications to Wine are submitted upstream if they're compatible with the goals and requirements of the larger Wine project; as a result, Wine users have been benefiting from parts of this work for over a year now. The rest is available as part of our source code repository for Proton and its modules.
