Yes, the lack of release fences is the very reason for the copy. I could
cook something up for the acquire fence, but that wouldn't synchronise the
buffer access anyway. The only way I can be sure the client doesn't
overwrite a buffer still in use by the GPU was to texture from a copy and
let the compositor release the original without waiting for the GPU and
without a fence.
