The panel drew each picture with SetOverlayRaw, a new texture upload every
time: the full calibration's 1024x768 picture flickered on every change, and
in a live test the headset kept showing the last calibration picture after the
panel had drawn the fit check (2026-10-01). Now, as screens/keyboard.cpp does,
it writes into three linear DMA-BUFs SteamVR imported once (the size of the
biggest panel; texture bounds show the part in use) and switches between them.
A show makes the overlay visible once its first picture is in.
The full calibration's and the five-dot check's dots wait for a left click or
Meta+J while you look at the dot, in place of capturing any steady gaze (which
can be a look somewhere else); no capture ring, no 8 s skip, and the check
closes after 2 minutes without a click. The quick check still captures itself.

ft-gazepanel (gaze/panel) is a SteamVR overlay that stays put in your view and
shows dots at known head-relative directions; the gaze service runs it and
drives it (gaze/gazecheck.py):
- a one-dot quick check 3 s after the headset goes on, when our tracker asks
for a click (reseat), at most every 2 minutes, and from Quick check on the
Gaze page; five dots follow if the next 3 lessons are still over 2 degrees off
- the full calibration (the probe's three rounds, dark to bright) when gaze mode
comes on without one, or from Calibrate; quitting it with still no calibration
turns gaze mode off
Each dot takes the gaze once it has held still for 0.6 s; a left click or Meta+J
takes it at once, a right click or Meta+K closes the panel (the pointer helper
hides its dot and passes those presses on while "calpanel" lasts). Our tracker
gets clicks and its own calibration; SteamVR's gets lessons per eye, or a new
calibration.json.

ft-gaze reads the Frame's eye tracker (SteamVR's eyetracking action and the
two gaze sets in eye-server.mmap, read only) and prints where the gaze lands
on the Frametop screens. ft-gazeprobe is a GTK playground on top of it: a
Vision Pro style calibration run, an accuracy test, refining the correction
model from logged points, and click, drag, and snap practice that learn the
tracker's error on the fly. It also follows SteamVR's eyetracking log for
restarts and the clicks SteamVR calibrates itself from, which it keeps only
in memory.
