/**
 * Structure specifying the coordinates of a sample location.
 * 
 * Description
 * 
 * The domain space of the sample location coordinates has an upper-left origin within the pixel in framebuffer space.
 * 
 * The values specified in a {@link VkSampleLocationEXT} structure are always clamped to the implementation-dependent sample location coordinate range [sampleLocationCoordinateRange[0],sampleLocationCoordinateRange[1]] that can be queried by chaining the {@link VkPhysicalDeviceSampleLocationsPropertiesEXT} structure to the {@code pNext} chain of {@link VkPhysicalDeviceProperties2KHR}.
 * 
 * See Also
 * 
 * {@link VkSampleLocationsInfoEXT}
 * 
 * Member documentation
 * 
 * 
 * {@code x} – the horizontal coordinate of the sample’s location.
 * {@code y} – the vertical coordinate of the sample’s location.
 * 
 * 
 * Layout
 * 
 *  * struct VkSampleLocationEXT {
 *     float x;
 *     float y;
 * }
