Android game always rotates to landscape orientation on startup

[dtaylorus]

When I'm holding the Android device in portrait orientation and start my game which also supports portrait orientation, the screen rotates to landscape for a couple of seconds before rotating back to portrait.

Expected: Start the game in portrait orientation and stay in portrait orientation without rotating to landscape.

The issue is that AndroidGameWindow.SetOrientation(DisplayOrientation newOrientation, ...) is initially called with newOrientation = DisplayOrientation.Default, which the method does not evaluate as a supported orientation and coerces into LandscapeLeft.

I resolved this issue by changing:

if ((supported & newOrientation) == 0)

to

if ((newOrientation != DisplayOrientation.Default) && (supported & newOrientation) == 0)

since DisplayOrientation.Default = 0 and doesn't otherwise pass the check for supporting any orientations.

Effectively, this makes DisplayOrientation.Default support any orientation instead of no orientations.
