            // than falling back to importing the AHwBuf using its external format (which is less
            // performant).

            // surfaces + images having an SkColorType that is compatible with a texture's native
            // format. When *creating* a Surface or Image from an AHwBuf-based BackendTexture, its

            // VK_FORMAT_B8G8R8A8_UNORM mapping to `GetSkColorTypeFromBufferFormat`. However, this
            // utility is public and shared b/w both ganesh and graphite. Adding this introduced
            // nontrivial complexity in ganesh (e.g., its SkImages::DeferredFromAHardwareBuffer API
            // does not know the AHwBuf format at creation). This could be worked around, but the
            // change would be more invasive and no clients have requested that we allow the use of
            // a driver's non-spec reported VkFormat equivalency in ganesh. Therefore, we simply
