    * What follows is a condensed summary, to help you navigate the large and
    * 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.
