[Mac] Retina screens not properly supported

I'm sure this is well known since the Retina display came out in 2012. The game doesn't properly support the resolution. You can set it to the correct res for the screen, but all the UI, especially the mouse, displays much too small. One solution might be to add a scaling bar for the mouse and other afflicted UI, as you can use the current scaling bars to adjust most of the UI but not all. The proper solution is to add a tidbit of logic in for detecting the 2x pixel density and doubling the scaling factor on all UI elements. The only (terrible) solution right now is to go down to a normal resolution for my physical screen dimensions and deal with a very blurry game. Kicks and giggles, this is the res that my screen is: 15" 2880x1800, and this is what the game has to run at: 1440x900

One more thing: I can't quite nail down the cause, but sometimes the screen will just freeze. Tabbing out and back in will fix it. While the screen is frozen, sound continues to play correctly but it doesn't appear that any controls still work.
