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

    *
    *   - 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.
    *
    *    - Loader interface v4 differs from v3 in:
    *        - The ICD must implement vk_icdGetPhysicalDeviceProcAddr().
    * 
    *    - Loader interface v5 differs from v4 in:
    *        - The ICD must support Vulkan API version 1.1 and must not return 
    *          VK_ERROR_INCOMPATIBLE_DRIVER from vkCreateInstance() unless a
    *          Vulkan Loader with interface v4 or smaller is being used and the
    *          application provides an API version that is greater than 1.0.
