// 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.
