/* NOTE ON VK_ANDROID_NATIVE_BUFFER_SPEC_VERSION 6
 *
 * This version of the extension transitions from gralloc0 to gralloc1 usage
 * flags (int -> 2x uint64_t). The WSI implementation will temporarily continue
 * to fill out deprecated fields in VkNativeBufferANDROID, and will call the
 * deprecated vkGetSwapchainGrallocUsageANDROID if the new
 * vkGetSwapchainGrallocUsage2ANDROID is not supported. This transitionary
 * backwards-compatibility support is temporary, and will likely be removed in
 * (along with all gralloc0 support) in a future release.
