The extents of the glyphs this Label will actually paint, given the content width it has been laid out at.
measured_width() above answers the width half of this question on its own; this also reports the painted height, the clamped line count, and where the ink lands.
intrinsic_width() answers a different question and deliberately returns 0 for a multi-line Label so the parent's available width drives wrapping — a Yoga contract, not a measurement. Anything that wants to know where the ink lands (does it collide with a sibling, does it run past its own box) therefore cannot use it: a multi-line Label reads as having no text at all. This runs the same shaper, the same own->inherited cascade, the same text-transform, the same break mode and the same line clamp that paint() does, and reports the result in the Label's LOCAL coordinates.
measured false means the extents are unknown (empty text), which is not the same as zero-sized and must never be reported as "no overlap".

Local box of the pixels paint() covers.
With Skia it is read back from one scratch paint, so overflow above a short box, glyph overhang and a captured line's position are all in it; without Skia it is the line block, with text-align applied to x.
