v1.17.0

• API improvements:
  • renderSVG* no longer requires the styles argument
  • Drawing.useHref can be set to use <use href=...> (SVG 2) instead of <use xlink:href=...> (SVG 1.1). This behaves better when embedding directly into HTML.
• Fix use of svgtiler on web (via <script> tag, no bundling)
  • Switch from setAttributeNS to setAttribute; only createElementNS seems to be needed/preferred
  • Workarounds for grapheme-splitter (with imperfect Unicode handling), prettify-xml (no prettification), and version number ((web))
