Fix #735: Illustrator EPS and .ai files match their page in Fit to Artwork Bounds and the page check

- Fit to Artwork Bounds fits the art exports draw: hidden objects and
  layers, guides and template layers don't count, and the bounds stop at
  a layer's clip.
- The comparison with the page catches an object one draws that the
  other doesn't (pixels whose neighbours all differ, away from type), a
  light colour against white, and, for an EPS whose page is its art's
  box, art the layers print outside it.
- textAs: outlines opens a .ai whose type shows from its PDF part, which
  has the outlines.
- document.open takes editingData: false to open an Illustrator EPS or
  .ai as its page or PDF part only, for print pipelines.

Part of #637.
