Layer 2 of docs/RUST.md's "Three test layers":
./run-headless.sh phone --phone --shot /tmp/p.png -- -p transcript-fixture
opens `transcript-fixture`'s screen -- the same fixture and the same
fold the headless tests and the Android bench use -- in a window at the
phone's own 1080x2424 and `content_scale` 2.55, and screenshots it. 15
seconds, warm. `--replay FILE` drives one of the `.touch` recordings
into it and writes `<shot>-before.png` too, so "the list moved" is two
pictures: the flick carries it back about seven turns of the fixture.
Two things this needed.
**The desktop backend now lays out in physical pixels with a density,
exactly as Android does** (`default::content_scale`, overridable with
`IRIS_SCALE`, which is how `--phone` hands it the phone's). It used to
divide winit's coordinates into a separate "logical" space, which left
`UiRenderState::resize` (physical, from `WindowEvent::Resized`) and the
window uniform (logical) disagreeing on any display whose scale factor
is not 1.0, and rasterised glyphs at one resolution to show them at
another. At 1.0 -- every display here -- the numbers are unchanged, and
the `tabs` screenshot is identical.
**`rig-input`'s `replay-touch`** puts a gesture on screen. This
machine's compositor has no pointer to move: sway runs on the headless
backend with no input devices, so `swaymsg seat - cursor press` reports
success and `swaymsg -t get_seats` shows `capabilities: 0`. wlroots 0.19
dropped `WLR_HEADLESS_INPUTS` and ydotool's uinput device would be
ignored by a compositor not reading libinput, so the virtual-pointer
protocol is what is left. It parses the *same* `TouchScript` the
harness does, so one recording drives both layers.
