and pointing go to the inputs bound to them; a key's press then its release when a message takes it; vega_frame sends dt 1/60 to the frame input, deferring the save as frames were; a table's pointer is the input pointing at it, sent the item's position; a key's handler found by its input's number

value's bidi within it
Speech wrote a value's C1 controls (U+009B is a CSI to some terminals),
DEL, line separators and bidi overrides as they were; the CLI and the
TUI wrote line separators (a pipe's reader may break its line there) and
the controls that turn text around (a terminal then reverses the rest of
its line, other values' cells too); the web page showed controls as they
were and let a label's override reverse its badge. Now every surface
shows controls, DEL, C1 and line and paragraph separators as pictures
(vega_visible); a terminal's cells show embeddings, overrides and
isolates as U+FFFD too (vega_cell); speech says a space for the one and
nothing for the other; the page shows the pictures and isolates each
value, while /screen's JSON keeps values as they are. screen_meaning
checks the CLI, the TUI, speech and the JSON against that rule, and that
nothing a value holds reaches any output as a control; the browser check
sees the page show it.

vega_draw keeps what it wrote as spans (VegaSpan: a row, the columns it
was given, where its cells reached, its text and tone). A span written
where the same pen stopped follows the one before it (a field's name and
value, the help line, the prompt); one written after the pen moved (a
table's column, a list's label, a badge) starts afresh at its column, and
a badge sits flush with its end.
When the first font shapes, the pixels set type: a span and those
following it are one line of text, laid out as one paragraph in the font
stack (bidi and kerning cross the spans; each glyph takes the tone of the
span its character came from), from its column up to the nearest of its
spans' ends and the next span on the row, cut at a grapheme cluster
boundary with an ellipsis if it must be. The prompt gets a text cursor.
--symbols repeats: fonts in order of preference (at most 8); the cells,
when the first font does not shape, also fall back through them.
The check sets a label in one script, alone in its list, and holds it to
what the font that has it sets by itself (vega-symbols paragraph, which
now sizes itself to its text with width 0), pixel for pixel: Latin
kerning, Hangul, Arabic and Devanagari over DejaVu Sans, Noto Sans CJK KR
and FreeSans.

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.
