* confusing official doc.
*
* - 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.
*
* - Loader interface v4 differs from v3 in:
