PdfSideViewer 0.7.0

PdfSideViewer shows two PDF documents side by side with synchronized scrolling that
survives different page formats and zoom levels: positions are exchanged in page units around
a user-adjustable anchor. Pure Win32 + Direct2D, a single portable executable.

New in 0.7.0

• UI in five languages: German, French and Hungarian join English and Italian
  (View ▸ Language). The switch is live and covers everything: menus with per-language
  mnemonics, toolbar labels and tooltips, dialogs, status bar, window title and the
  Explorer context-menu verbs; accelerator key names follow each language's Windows
  convention (Strg+Umschalt, Ctrl+Maj, ...).
• Bookmark matching across five languages: "Sync Points from Bookmarks" now
  recognizes verbal numbering prefixes in Italian, English, German, French and
  Hungarian ("Chapter 3" = "Kapitel 3" = "Chapitre 3" = "Fejezet 3"), and unnumbered
  front/back-matter sections pair with their translation ("Indice" = "Contents" =
  "Inhaltsverzeichnis" = "Table des matières" = "Tartalomjegyzék"; likewise preface,
  bibliography, index, glossary, list of figures and friends).
• LaTeX-style appendix sub-items: lettered bookmarks ("A ...", "B ...") under an
  appendix heading pair by their letter across translations.
• Safer title pairing: unnumbered bookmarks only pair at the same outline depth, so
  a top-level section can never anchor to a nested homonym and skew a whole segment.
• Locale-proof matching: bookmark tokenization and case-folding use deterministic
  Unicode classification and invariant-locale lowercasing, so generated sync points are
  identical on every host Windows language.
