/**
 * The unit endpoints of `linearGradientGeometry` projected onto a box, in user
 * space. For `gradientUnits="userSpaceOnUse"`, which is what an SVG emitter
 * needs when the gradient must span something OTHER than each referencing
 * element's own bounding box — curved text is drawn as one `<text>` per glyph,
 * so the default objectBoundingBox units would give every letter its own full
 * colour ramp instead of one ramp across the word.
 *
 * Shared so the string emitter (core's createSVGGradientDef) and the VNode one
 * (svg-export's) cannot drift on the arithmetic.
