30 // Version 0 - Initial. Doesn't support vk_icdGetInstanceProcAddr
31 // or vk_icdNegotiateLoaderICDInterfaceVersion.
32 // Version 1 - Add support for vk_icdGetInstanceProcAddr.
33 // Version 2 - Add Loader/ICD Interface version negotiation
34 // via vk_icdNegotiateLoaderICDInterfaceVersion.
35 // Version 3 - Add ICD creation/destruction of KHR_surface objects.
36 // Version 4 - Add unknown physical device extension qyering via
37 // vk_icdGetPhysicalDeviceProcAddr.
38 // Version 5 - Tells ICDs that the loader is now paying attention to the
39 // application version of Vulkan passed into the ApplicationInfo
40 // structure during vkCreateInstance. This will tell the ICD
41 // that if the loader is older, it should automatically fail a
42 // call for any API version > 1.0. Otherwise, the loader will
43 // manually determine if it can support the expected version.
