/*
 * 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.

/*
 * 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.
