📣 borb release 2.0.13

With this release, borb is one step closer to being able to write a PDF/A-1b document.
We still need to create an \OutputIntents Dictionary in the document to be fully compliant.
This is planned for the next release.

This release features:

• Minor bugfix to estimating width of a space character
  • Useful in text extraction
• Bugfix in TrueTypeFont to build a proper \Widths array and cmap
• Fixes in XMPDocumentInfo class
  • Title
  • Author
  • Creator
  • CreatorTool
• Separate logic that writes \Info Dictionary
  • This class now also writes the XMP \Metadata when needed
  • Enables PDF/A-1b
  • Added tests for PDF/A-1b (preservation of metadata)
