  Reimplement WindowSurfaceVkAndroid::getCurrentWindowSize()
  
  Use vkGetPhysicalDeviceSurfaceCapabilitiesKHR() instead of
  ANativeWindow_getWidth() & ANativeWindow_getHeight().  The former
  gives the proper size of the window, where the latter gives the size
  of the device's display (which is the default size of a window).
