// headers for different platforms are supplied. They provide just the types

// When a new Vulkan platform is defined, the corresponding USE_PLATFORM
// header definition, and any supporting fake platform headers, should be
// defined here, along with a trivial compilation test using a Vulkan type
// or function specific to that platform.
