  Message : WinRT: fixed bug whereby SDL would override an app's default orientation 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!

  OpenGL ES 2.x support
  ================================================================================
  
  SDL has support for OpenGL ES 2.x under Windows via two alternative 
  implementations. 
  The most straightforward method consists in running your app in a system with 
  a graphic card paired with a relatively recent (as of November of 2013) driver 
  which supports the WGL_EXT_create_context_es2_profile extension. Vendors known 
  to ship said extension on Windows currently include nVidia and Intel.
  
  The other method involves using the ANGLE library (https://code.google.com/p/angleproject/)
  If an OpenGL ES 2.x context is requested and no WGL_EXT_create_context_es2_profile
  extension is found, SDL will try to load the libEGL.dll library provided by
  ANGLE.
  To obtain the ANGLE binaries, you can either compile from source from
  https://chromium.googlesource.com/angle/angle or copy the relevant binaries from
  a recent Chrome/Chromium install for Windows. The files you need are:
      
      * libEGL.dll
      * libGLESv2.dll
      * d3dcompiler_46.dll (supports Windows Vista or later, better shader compiler)
      or...
      * d3dcompiler_43.dll (supports Windows XP or later)
      
  If you compile ANGLE from source, you can configure it so it does not need the
  d3dcompiler_* DLL at all (for details on this, see their documentation). 
  However, by default SDL will try to preload the d3dcompiler_46.dll to
  comply with ANGLE's requirements. If you wish SDL to preload d3dcompiler_43.dll (to
  support Windows XP) or to skip this step at all, you can use the 
  SDL_HINT_VIDEO_WIN_D3DCOMPILER hint (see SDL_hints.h for more details).
  
  Known Bugs:
      
      * SDL_GL_SetSwapInterval is currently a no op when using ANGLE. It appears
        that there's a bug in the library which prevents the window contents from
        refreshing if this is set to anything other than the default value.
