1856    *
1857    *   - Loader interface v0 is incompatible with later versions. We don't
1858    *     support it.
1859    *
1860    *   - In loader interface v1:
1861    *       - The first ICD entrypoint called by the loader is
1862    *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1863    *         entrypoint.
1864    *       - The ICD must statically expose no other Vulkan symbol unless it is
1865    *         linked with -Bsymbolic.
1866    *       - Each dispatchable Vulkan handle created by the ICD must be
1867    *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1868    *         ICD must initialize VK_LOADER_DATA.loadMagic to ICD_LOADER_MAGIC.
1869    *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1870    *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1871    *         such loader-managed surfaces.
1872    *
1873    *    - Loader interface v2 differs from v1 in:
1874    *       - The first ICD entrypoint called by the loader is
1875    *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1876    *         statically expose this entrypoint.
1877    *
1878    *    - Loader interface v3 differs from v2 in:
1879    *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1880    *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1881    *          because the loader no longer does so.
