This is an overdue fix.
We previously did our own scan of the page's appearance source to identify text rendering mode specifications.

This fix directly uses redactions annotations to remove hidden text. The term "hidden" now also include a larger scope:

  • Text written with Tesseract's GlyphLessFont
  • Text that is neither "filled" nor "stroked"
  • Text that has alpha=0 (fully transparent)
