Blobby Tennis supports macOS!

I finally ported Blobby Tennis to macOS, making it one of the first SteamVR games for macOS!

It requires a Vive and SteamVR and either a strong dedicated or an external GPU. My MacBooks AMD Pro 460 is the minimum it requires to keep consistent 90fps.

I had do make some tradeoffs for performance compared to the windows version:

• 4x MSAA instead of 8x MSAA
• No preview window (the window compositor took randomly too much time every couple of frames)

The performance on windows should also have improved a bit due to more optimizations. Also the SteamVR supersampling setting can now be adjusted with realtime feedback, without requiring a restart of the game.

Let me know if you encounter any issues!
