iris
9d13f15bee
A rendering claim about iris was verified by hand from another checkout, because the compositor script and the input replay lived in ai-app's submodule and not here. `scripts/run-headless.sh` starts a headless sway on its own socket, runs an example against it and screenshots the result. `rig-input`'s `replay-touch` drives a recorded gesture in through Wayland's virtual pointer, since a headless compositor has no input device to move. `iris::harness` gains the `.touch` parser, so a recording means the same thing replayed into a harness as into a window rather than being read twice by two parsers. The ai-app copy's `--phone` became `--mode`, since which phone is not iris's business; its `IRIS_SCALE` has nothing to hand a density to here, so it waits for one.
