v4.20.1

• A selection in a PDF covers the spaces between words, and no longer drifts to the
  right along a line.
• Dragging a selection in a PDF over blank space or a link no longer jumps to the
  start or the end of the page.
• A drawing on a PDF lands where the finger went when the page is zoomed to fit.
• More PDFs open: some that failed before now open, a scanned page stored as a fax
  shows where it used to be blank, and the text of a PDF made by an old Ghostscript
  shows.
• A scanned PDF opens faster.
• A Markdown file keeps side margins, like other documents, when the margins are on.
• 4.20.0 was held before it reached the store, so its changes reach the store here.
