Description Ethan Lee 2013-06-20 01:12:14 UTC 
The problematic revision: http://hg.libsdl.org/SDL/rev/a8145f734ad3

After this revision, moving the 360 controller's left stick to the bottom (maximum Y value) overflows to -32768. 

Was there a specific case that caused this change?

This is what we're doing in MG-SDL2 with GameController:

https://github.com/flibitijibibo/MonoGame/blob/monogame-sdl2/MonoGame.Framework/SDL2/Input/SDL2_GamePad.cs#L656

Should we be doing something else (besides being ashamed of ourselves for all the casting)?
