2.4 History

    Please read the history bottom-up. Note that the history might list some
    features that were implemented in beta versions and removed later but are
    still mentioned here. This history is a log of the programmer so that he
    can look up what has been done/tried/modified. Things that were implemented
    and removed later are marked with [VOID].

    Version 1.3   (05-Dec-20)
    - Change: Updated documentation
    - Change: Amiga installer will now also copy the plugins for all platforms to Hollywood's linker plugins
      directory so that they can be easily linked to executables (suggested by kas1e)
    - Fix: pdf.GetPageLen() and pdf.GetText() didn't skip potential control characters in the text correctly
      (reported by Petteri Valli)
    - Fix: doc:SaveToFile() wasn't compatible with virtual files (reported by Jean Holzammer)
    - New: When loading PDFs as animations using @ANIM or LoadAnim(), Polybios will create vector animations
      now if a Hollywood version that supports vector animations is installed; if you don't want that, pass
      TRUE in the new "NoVectorAnim" tag to @REQUIRE
    - New: Polybios supports Hollywood Designer 5 now; note that it won't be loaded automatically because
      of its size; you need to manually tell Designer to load it in Designer's settings
      
    Version 1.2   (11-Aug-19)
    - Change: Updated documentation
    - Fix: pdf.GetLastError() will now return #PDFERR_SUCCESS (0) in case pdf.OpenDocument() succeeded
      (reported by Petteri Valli)
    - New: Added pdf.GetMediaBox() to get a page's media box and pdf.GetCropBox() to get a page's crop box
    - New: Added pdf.PageToDevice() function and pdf.DeviceToPage(); these can be used to convert coordinates
      from page to device space and vice versa
    - Fix: pdf.GetPageLinks() and its counterpart in pdf.GetBrush() didn't parse all page links correctly
      (reported by Petteri Valli)
    - Fix: pdf.GetBookmarks() didn't make sure that there was enough stack space for the bookmark table
      (reported by Petteri Valli)
       
    Version 1.1   (21-Jun-19)
    - Change: Updated documentation
    - Change [Examples]: PDF Viewer example supports password-protected PDFs now
    - New [Amiga]: Added "KillExt" tool to distribution archive; this can be used to flush Polybios.ext
      from memory; Polybios keeps this in memory for performance reasons but it will require about 6 MB
      of memory; only ever use KillExt if all resources used by Polybios.ext have been released first
    - Fix [Amiga]: Automatic platform selector in installer didn't work correctly
    - Fix [Amiga]: ".." and "." weren't handled correctly in filename specifications
    - New [Amiga]: Added version string to Polybios.ext
    - New: Added new attributes for GetAttribute(): #PDFATTRVERSION returns the document's PDF version
      and #PDFATTRPERMISSIONS returns its permissions
    - New: Added pdf.GetLastError(); this can be called if pdf.OpenDocument() fails to get extended error
      information; if it returns #PDFERR_PASSWORD, the document couldn't be opened because it's password
      protected
    - New: Added pdf.GetPageLabel() which can be used to get labels from PDF pages
    - New: Added pdf.GetMetaText() which can be used to get meta-data from a PDF document
    - New: Added pdf.GetBookmarks() function; this will return a table containing all bookmarks used by
      the PDF document as well as their targets; the table returned by this function is similar to the one
      returned by pdf.GetPageLinks(), except that bookmarks can be nested
    - New: Added the following functions for searching PDF pages for text: pdf.FindStart(), pdf.FindNext(),
      pdf.FindPrev(), pdf.GetFindResult()
    - New: Added the following functions to deal with text on a page: pdf.GetPageLen(), pdf.GetText(),
      pdf.GetCharBox(), pdf.GetCharOrigin(), pdf.GetCharIndexAtPos(), pdf.GetRects(), pdf.GetBoundedText();
      these functions can be used to retrieve text from a PDF page as well as its position
    - New: Added pdf.GetPageLinks() function; this will return a table containing all links in a page and
      their targets
    - New: Added pdf.LoadPage() and pdf.FreePage() for fine-tuned control over page loading; also added
      pdf.GetBrushFromPage() for getting brushes from pages loaded using pdf.LoadPage()
    - New: Added pdf.IsPDF() function; this can be used to check if the specified file is a PDF document
      (requested by Petteri Valli)
    - Fix [Amiga]: Polybios didn't exit cleanly when opened by hosts that use a pre-Hollywood 6.0 plugin
      interface (e.g. Hollywood Designer or executables compiled by Hollywood < 6.0) (reported by Petteri
      Valli)
    - New: Added optional argument to pdf.GetBrush(); if this is set to TRUE, pdf.GetBrush() will return
      an additional table that contains a collection of all links in the page; the table will contain
      information about the position, type, and target of each link in the page (requested by Petteri Valli)
    - Change [68k]: Recompiled with Bebbo's latest gcc 6 for 68k; WinUAE users note that you'll need at
      least WinUAE 4.2.1 for Polybios now because older versions had a bug in the 68020 emulation which can
      make Polybios crash
    - Fix [BigEndian]: Password-protected PDFs couldn't be opened on big endian architectures because of
      an endian issue in the encryption key generator in PDFium; this will also fix some other non-password
      protected PDFs; when will people learn to write endian-independent code? (reported by Petteri Valli)
    - Fix: pdf.GetBrush() trashed memory when the destination brush was a brush created by pdf.GetBrush()
      (reported by Petteri Valli)
    - Fix [Amiga]: Polybios.ext couldn't be correctly loaded from a path with spaces (e.g. "RAM Disk:")
      (reported by Frank Mariak)
     
    Version 1.0a  (28-Jun-18)
    - No version bump to 1.1 because only the Amiga versions have been changed and I'm too lazy
      to re-compile all other platforms just for an updated version string
    - Fix [Amiga]: pdf.OpenDocument() didn't work with filenames with non-ASCII characters
      (reported by Rafal Chyla)
    - New [OS3]: Added 68881/2 FPU build of Polybios; especially the PDF renderer is a lot
      faster when using the FPU version
    - New [OS3]: The AmigaOS 3.x version of Polybios supports PDF rendering now; thanks a lot
      to Stefan "Bebbo" Franke for his work on gcc 6.4 for m68k which made this possible!;
      NB: if you intend to use the 68k version on OS4 (which doesn't really make sense, but
      anyhow), you have to turn off the JIT for LIBS:Hollywood/Polybios.ext because with JIT
      Petunia seems to be stuck in an endless loop; on MorphOS the 68k PDF renderer won't
      work either but this looks like a bug in MorphOS' 68k emulation to me; on WinUAE it
      works fine
     
    Version 1.0   (21-Apr-18)
    - First Release
