Hi Lionel,
This doesn't apply cleanly to 18.1, it would at the very least need "anv: Allow
blitting to/from any supported format" to apply cleanly, but I suspect that
would in turn require a bunch of blorp patches. If you'd like this pulled into
18.1 please provide a backport or a list of patches you'd like applied,
otherwise I'll just ignore this.
