ForeignObjectMetrics	novasvg::measureForeignObjectSegments (std::string_view rawHtml, const std::vector< ForeignObjectSegment > &segments, const ForeignObjectFonts &fonts, unsigned char baseStyle, float maxWidth)
	Measures what ForeignObjectMetrics::height (etc.) will be for rawHtml painted with font, using the exact same foreignObjectPlainText() / wrapForeignObjectText() / foreignObjectLineHeight() logic ForeignObjectSimple::render() itself calls – so a value computed here and a box later painted by novasvg with the same (rawHtml, font) can never disagree, short of a bug in this shared logic itself.
ForeignObjectMetrics	novasvg::measureForeignObjectContent (std::string_view rawHtml, const ForeignObjectFonts &fonts, float maxWidth=-1.f, unsigned char baseStyle=0)
	measureForeignObjectContent() for text that may carry bold and italic: fonts supplies the face for each style (see ForeignObjectFonts; SVGForeignObjectElement::fontsFor() builds it the way painting does), baseStyle is the style the foreignObject itself has. This is exactly what painting does, so the metrics and the painted box cannot disagree about a bold label being wider than a regular one.
ForeignObjectMetrics	novasvg::measureForeignObjectContent (std::string_view rawHtml, const Font &font, float maxWidth=-1.f)
	measureForeignObjectContent() with a single face: every style is measured with font, i.e. as if the text had no bold or italic in it. Line breaks and heights are unaffected by bold or italic; only the widths of styled stretches can differ from what painting produces, by however much the real bold/italic faces differ from font. Use the ForeignObjectFonts overload when that matters.
