// Loader-ICD version negotiation API.  Versions add the following features:
//   Version 0 - Initial.  Doesn't support vk_icdGetInstanceProcAddr
//               or vk_icdNegotiateLoaderICDInterfaceVersion.
//   Version 1 - Add support for vk_icdGetInstanceProcAddr.
//   Version 2 - Add Loader/ICD Interface version negotiation
//               via vk_icdNegotiateLoaderICDInterfaceVersion.
//   Version 3 - Add ICD creation/destruction of KHR_surface objects.
//   Version 4 - Add unknown physical device extension qyering via
//               vk_icdGetPhysicalDeviceProcAddr.
//   Version 5 - Tells ICDs that the loader is now paying attention to the
//               application version of Vulkan passed into the ApplicationInfo
//               structure during vkCreateInstance.  This will tell the ICD
//               that if the loader is older, it should automatically fail a
//               call for any API version > 1.0.  Otherwise, the loader will
//               manually determine if it can support the expected version.
//   Version 6 - Add support for vk_icdEnumerateAdapterPhysicalDevices.
