The terminal, the pixel surfaces and the web page reckoned when a timer
was due on the wall clock: set back, a timer waited until the clock came
again to the tick it had waited for (Pure's review 004). vega_clock is
the monotonic clock; timers are due on it, and a tick sets the time its
event sees from the wall clock (vega_now), as before.
check.py's clock_set_back runs a timer of 20 ms in the terminal with the
wall clock set back an hour 0.2 s in (Pure's build/clock-back.so, an
LD_PRELOAD of clock_gettime): 40 ticks in 0.8 s, where Vega before this
stops at 9. make check passes it --clock-back.

Chromium's accessibility tree
Lists are listboxes that keep the keyboard focus, the focused row their
active descendant, each option with its place in the whole list though
only the visible rows are drawn; tables are grids with row indices;
tones other than normal and muted are said, not only coloured; keys are
named buttons. The page now updates in place instead of rebuilding each
list, so the focus a screen reader follows survives every redraw. The
browser test reads Chromium's accessibility tree: roles, names, focus,
selection and the active descendant moving within the same list.

src/ held two parts, the surfaces that show modules to people and the
symbol format with its CPU and GPU drawing. As in Pure (design 009), top
level directories are now the parts, and the README says what each builds.
