3562 * entrypoint.
3563 * - The ICD must statically expose no other Vulkan symbol unless it is
3564 * linked with -Bsymbolic.
3565 * - Each dispatchable Vulkan handle created by the ICD must be
3566 * a pointer to a struct whose first member is VK_LOADER_DATA. The
3567 * ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
3568 * - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
3569 * vkDestroySurfaceKHR(). The ICD must be capable of working with
3570 * such loader-managed surfaces.
3571 *
3572 * - Loader interface v2 differs from v1 in:
3573 * - The first ICD entrypoint called by the loader is
3574 * vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
3575 * statically expose this entrypoint.
3576 *
3577 * - Loader interface v3 differs from v2 in:
3578 * - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
3579 * vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
3580 * because the loader no longer does so.
