# Build ft-gaze and the calibration panel ft-gazepanel in the dev container on the Frame
# (gaze/build/; they also run there). The panel draws its text with stb_truetype (public
# domain, one header, pinned as in screens/build.sh).
# The eye tracking API (IVRInput::GetEyeTrackingDataRelativeToNow) is newer than the header
# shipped with SteamVR's samples, so this uses the pinned public header ft-screens fetches.
