1857    *
1858    *   - Loader interface v0 is incompatible with later versions. We don't
1859    *     support it.
1860    *
1861    *   - In loader interface v1:
1862    *       - The first ICD entrypoint called by the loader is
1863    *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1864    *         entrypoint.
1865    *       - The ICD must statically expose no other Vulkan symbol unless it is
1866    *         linked with -Bsymbolic.
1867    *       - Each dispatchable Vulkan handle created by the ICD must be
1868    *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1869    *         ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
1870    *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1871    *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1872    *         such loader-managed surfaces.
1873    *
1874    *    - Loader interface v2 differs from v1 in:
1875    *       - The first ICD entrypoint called by the loader is
1876    *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1877    *         statically expose this entrypoint.
1878    *
1879    *    - Loader interface v3 differs from v2 in:
1880    *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1881    *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1882    *          because the loader no longer does so.
