	*
	*   - Loader interface v0 is incompatible with later versions. We don't
	*     support it.
	*
	*   - In loader interface v1:
	*       - The first ICD entrypoint called by the loader is
	*         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
	*         entrypoint.
	*       - The ICD must statically expose no other Vulkan symbol unless it is
	*         linked with -Bsymbolic.
	*       - Each dispatchable Vulkan handle created by the ICD must be
	*         a pointer to a struct whose first member is VK_LOADER_DATA. The
	*         ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
	*       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
	*         vkDestroySurfaceKHR(). The ICD must be capable of working with
	*         such loader-managed surfaces.
	*
	*    - Loader interface v2 differs from v1 in:
	*       - The first ICD entrypoint called by the loader is
	*         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
	*         statically expose this entrypoint.
	*
	*    - Loader interface v3 differs from v2 in:
	*        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
	*          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
	*          because the loader no longer does so.
