[AD] MacOS X GameController API

[Max Savenkov <max.savenkov@xxxxxxxxxx>]

MacOS X 10.9+ has the new GameController framework 
(https://developer.apple.com/library/mac/documentation/GameController/Reference/GameController_RefColl/index.html), 
which allows very simple handling of gamepads (compared to old HID 
code). It also supports all XBox-compatiable devices, as far as I can 
tell (unlike HID code, which fails to recognize my Logitech F310). 
However, it's somewhat limited in what it can do. For example, it does 
not support Start/Back buttons, to say nothing of Guide/XBox/etc button. 
It also does not support thumbsticks-as-buttons.

So, my question is: would it make any sense to write a driver for 
Allegro to support this API (and XBox-like gamepads), or does its 
limitations make it useless?
