A text was drawn into a texture as tall as Pixi measures the string
"|ÉqÅM". Whatever reached further, like the "g" of Manrope (0.015 em
below the "q"), was cut off at the bottom. The blue frame around a
text was only estimated from the font size and the number of letters,
so it was far too wide for most texts.
- textPicture.ts takes the height of a line from the font itself
(fontBoundingBoxAscent and fontBoundingBoxDescent, as a browser
does). Pixi draws with a margin, and the picture is cut to that box
afterwards. Where Pixi's own box is larger, Pixi's box wins.
- Both raster paths (linear and nearest) use the cut.
- The height no longer depends on the letters typed, so a text does
not jump while it is edited.
- bounds.ts asks a measurer that textPicture.ts registers
(setTextMeasure). Selection, picking in a running game, framing the
camera, the drop preview and culling all get the measured size.
The footprint functions take the font file for this.
- Unit tests in node have no canvas and keep the estimate
(estimatedTextSize).
- Texts get taller: Source Sans 3 at 48 px is 68 instead of 55 px,
Manrope is 1.366 em instead of 1.25 em. The glyphs stay in place,
the centre moves by less than half a pixel. A shader on a text
gets a taller UV rectangle.
Tests:
- Gate on melektaus-atx green: 307 files, 4762 tests.
- 5 new unit tests for textBox, textCut and the measurer hook.
- e2e 30: 26 checks, 30f-iii new. The texture is 68 high, the font
box is 68, the frame equals the drawn picture (237x68).
- Counter test: with Pixi's old box the texture is 55 high and
30f-iii is red.
- Not checked in the browser: the Manrope caption of the user and
texts with several lines.

The Feuerwerk wordmark is set with -0.03em tracking. Text in the
engine had no letter spacing, so the wordmark came out about 3 % wider
than the logo.
- Text has a new property Letter spacing, default 0, in the same unit
as the font size. It goes between each two characters, so ten
characters get it nine times. Negative values pull them together.
- TextPicture hands the value to Pixi's text style. Both rasters, the
smooth and the sharp one, use it, and it is part of the raster key.
- The estimated text width in bounds.ts adds the spacing too, so
selection, picking and "Add collider" fit the drawn text.
- Like every number property it can be animated and set from a graph.
That is not tried in the browser.
Tests:
- New unit test for the footprint with spacing. 102 tests in the
three text files green.
- e2e 30f-ii measures the width of "Handgloves" on screen: 237 without
spacing, 282 at +5 (expected +45) and 210 at -3 (expected -27).
e2e 30 on melektaus-atx: ALL PASSED, 25 checks.
- Gate on melektaus-atx: CHECK EXIT 0, 307 files, 4757 tests.
- No counter-check run for 30f-ii.

Get/Set property, Get/Set properties, Set enabled and Set text are gone.
A single Properties node takes a fixed "object" input; every chosen
property is an output that reads the current value, and one switched to
Set is also an input written when the flow arrives. Exec pins only exist
while at least one entry writes.
The node carries a type (Sprite, Text, Collider, Camera, Container,
Behavior, Any) that decides what "+ Property" offers: the fields of that
type, the variables of the chosen behavior, or for Any a kind to pick
and a name to type. Each port takes the default and field of its type,
so a Camera width starts at 640. Switching the type keeps the ports and
marks those the new type lacks. At runtime the type is only an editor
aid; the node writes to whatever object it gets.
Old project files are converted on load. The type is inferred from the
keys: the first object type that has them all, else the one behavior
that declares them all, else Any. enabled belongs to every object, so a
converted Set enabled lands on Any.
The jump-run and tetris seeders use Properties throughout; draw-piece
switches its cell on in the same node that sets the colour.
