The tracked hands arrive 30-60 ms after the cameras saw them and reach the
displays later still, so holes trailed moving hands. Track each hand's palm
velocity in the room and move its capsules ahead to about when the frame is
on the displays, every tick, so the holes also move smoothly between tracker
updates. Slow hands aren't moved (their velocity is noise). The control
socket gets cutouts predict on|off and cutouts lead <ms>.

A capsule end near the eyes' plane projects far across a screen with a huge
radius, so one bad hand estimate there tore a hole through the screens for a
moment. Clip capsules 12 cm in front of the eye, as the tracker now does too.

Where frame-hands tracks a hand between an eye and a screen, that eye sees the
room through the screen. handcut.cpp draws the screen's buffer side by side
(one half per eye) with the hands cut out, only while a hand is in front of it.
The cutouts command turns it on or off. ft-handtest tries it on a test panel.
Not yet tested in the headset.
