"""Schema 6: tracing is a symbol.
|
|
|
|
A face's `:head :trace` is gone: its footage is a placement of a `:type :trace`
|
|
symbol under the head, the trace keys are that placement's `:time :holds`, and the
|
|
head follows them with `:reads`. Nothing is converted. Every project is marked 6,
|
|
and one that still carries a `:trace` is refused when it is opened, by name and
|
|
with what to do about it; the rest open as they did.
|
|
|
|
Images are stills to trace over, stored like sounds.
