From Tomas Hogarth, "Attached are the complete changed files GraphicsWindowIOS and GraphicsWindowIOS.mm. The change is in regard to the ability to adapt to device orientation. We did just have a bool indicating the window would adapt to all orientations. I have changed this to a bit mask allowing the user to specify individual orientations or combinations.

enum DeviceOrientation{

                    PORTRAIT_ORIENTATION = 1<<0,

                    PORTRAIT_UPSIDEDOWN_ORIENTATION  = 1<<1,

                    LANDSCAPE_LEFT_ORIENTATION  = 1<<2,

                    LANDSCAPE_RIGHT_ORIENTATION  = 1<<3,

                    ALL_ORIENTATIONS = PORTRAIT_ORIENTATION  | PORTRAIT_UPSIDEDOWN_ORIENTATION  | LANDSCAPE_LEFT_ORIENTATION  | LANDSCAPE_RIGHT_ORIENTATION

                };

                typedef unsigned int DeviceOrientationFlags;

The main motivation for this is to easily allow the user to specifiy that the device is in a horizontal orientation rather then having to rotate the view matrix. All flags have been tested individually as well as in combinations. The default is ALL_ORIENTATIONS to keep the exiting functionality for anyone who hasn't specified WindowData for their context traits.
