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.
