- Breaking change: Avoid adding assignAttributes, addSVGElementFromJson,

`call`, `copyElem`, `findDefs`, `getElem`, `getId`, `getIntersectionList`,
  `getMouseTarget`, `getNextId`, `getUrlFromAttr`, `hasMatrixTransform`,
  `matrixMultiply`, `recalculateAllSelectedDimensions`,
  `recalculateDimensions`, `remapElement`, `removeUnusedDefElems`, `round`,
  `runExtensions`, `sanitizeSvg`, `setGradient` `transformListToTransform`
  (and mistaken `toString` export) to `getPrivateMethods` (passed to
  extensions) as available as public ones
- Build: Update ext-xdomain-messaging
- Fix (extension): ForeignObject editor
- Docs: Avoid reporting deliberate "Any" type
- Docs: Further docs (`logMatrix`, `getPrivateMethods`)
- Docs: Suggest `npm pack`
