  // The following properties can be set on the CoreApplication to support additional
  // ANGLE configuration options.
  //
  // The Visual Studio sample templates provided with this version of ANGLE have examples
  // of how to set these property values.
  
  //
  // Property: EGLNativeWindowTypeProperty
  // Type: IInspectable
  // Description: Set this property to specify the window type to use for creating a surface.
  //              If this property is missing, surface creation will fail.
  //
  const wchar_t EGLNativeWindowTypeProperty[] = L"EGLNativeWindowTypeProperty";
  
  //
  // Property: EGLRenderSurfaceSizeProperty
  // Type: Size
  // Description: Set this property to specify a preferred size in pixels of the render surface.
  //              The render surface size width and height must be greater than 0.
  //              If this property is set, then the render surface size is fixed.
  //              The render surface will then be scaled to the window dimensions.
  //              If this property is missing, a default behavior will be provided.
  //              The default behavior uses the window size if a CoreWindow is specified or
  //              the size of the SwapChainPanel control if one is specified.
  //
  const wchar_t EGLRenderSurfaceSizeProperty[] = L"EGLRenderSurfaceSizeProperty";
  
  //
  // Property: EGLRenderResolutionScaleProperty
  // Type: Single
  // Description: Use this to specify a preferred scale for the render surface compared to the window.
  //              For example, if the window is 800x480, and:
  //                - scale is set to 0.5f then the surface will be 400x240
  //                - scale is set to 1.2f then the surface will be 960x576
  //              If the window resizes or rotates then the surface will resize accordingly.
  //              EGLRenderResolutionScaleProperty and EGLRenderSurfaceSizeProperty cannot both be set.
  //              The scale factor should be > 0.0f.
