1869     * What follows is a condensed summary, to help you navigate the large and
1870     * confusing official doc.
1871     *
1872     *   - Loader interface v0 is incompatible with later versions. We don't
1873     *     support it.
1874     *
1875     *   - In loader interface v1:
1876     *       - The first ICD entrypoint called by the loader is
1877     *         vk_icdGetInstanceProcAddr(). The ICD must statically expose this
1878     *         entrypoint.
1879     *       - The ICD must statically expose no other Vulkan symbol unless it
1880     * is linked with -Bsymbolic.
1881     *       - Each dispatchable Vulkan handle created by the ICD must be
1882     *         a pointer to a struct whose first member is VK_LOADER_DATA. The
1883     *         ICD must initialize VK_LOADER_DATA.loadMagic to
1884     * ICD_LOADER_MAGIC.
1885     *       - The loader implements vkCreate{PLATFORM}SurfaceKHR() and
1886     *         vkDestroySurfaceKHR(). The ICD must be capable of working with
1887     *         such loader-managed surfaces.
1888     *
1889     *    - Loader interface v2 differs from v1 in:
1890     *       - The first ICD entrypoint called by the loader is
1891     *         vk_icdNegotiateLoaderICDInterfaceVersion(). The ICD must
1892     *         statically expose this entrypoint.
1893     *
1894     *    - Loader interface v3 differs from v2 in:
1895     *        - The ICD must implement vkCreate{PLATFORM}SurfaceKHR(),
1896     *          vkDestroySurfaceKHR(), and other API which uses VKSurfaceKHR,
1897     *          because the loader no longer does so.
