WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!

This file simply contains a function for determining whether a dependency

exists on the Windows platform, given a possible environmental variable,

delimited search paths, and a main and/or sub-directory paths for more

elaborate pattern matching.
