39  * to fill out deprecated fields in VkNativeBufferANDROID, and will call the
40  * deprecated vkGetSwapchainGrallocUsageANDROID if the new
41  * vkGetSwapchainGrallocUsage2ANDROID is not supported. This transitionary
42  * backwards-compatibility support is temporary, and will likely be removed in
43  * (along with all gralloc0 support) in a future release.
