cpan:WARRINGD
0.5.15  2021-10-15T07:45:19+13:00
    - Add load-font(:$prefix) option. To enable a pre-determined prefix (6
      upppercase letters) for subsetted fonts. Used in the test-suite to
      create stable PDF files, without any random characters.
    - Fix font encoding issue #12

0.5.14  2021-10-09T09:02:52+13:00
    - Detect WOFF fonts and disable embedding.
    - Performance improvement to CID fonts

0.5.13  2021-08-05T12:36:58+12:00
    - Fix PDF::Class compatibility by ensuring /Type0 (CID) font
      dictionaries are created with all mandatory fields in place.

0.5.12  2021-08-03T17:31:00+12:00
    - Change Glyph width and height attributes from dx(), dy() to ax() ay()
      for consistency with HarfBuzz module.
    - Initialize FontDescriptor with a /FontName entry (required field)

0.5.11  2021-08-03T12:24:32+12:00
    - Fix CMap code ranges to encode and decode as UTF16BE. See
      ISO-32000 9.10.3 ToUnicode CMaps
    - Disable writing of experimental utf8, utf16 and utf32 encodings
      for now. Sticking point is creating a ToUnicode CMap that works
      across all code ranges.

0.5.10  2021-07-31T10:50:31+12:00
    - Fix PDF::Font::Loader::Enc::Unicode decode() method

0.5.9 
    - Add PDF::Font::Loader::Enc::Unicode encoder (experimental) for reading and
      writing utf8, utf16 and utf32 encodings and CMaps
    - Handle input and output of Type0 fonts with potentially separate /ToUnicode
      and /Encoding CMaps. Also secondary CMaps referenced via /UseCMap from the
      main CMap.

0.5.8  2021-07-21T14:08:58+12:00
    - Fix reading and writing of CMap code space ranges for conformance with
      https://adobe-type-tools.github.io/font-tech-notes/pdfs/5014.CIDFont_Spec.pdf

    - Fix glyph lookup for an embedded font without a char-map.

0.5.6  2021-07-13T13:40:44+12:00
   - Tweak loading of CID fonts from font dictionaries.
   - Documentation. README.md has been split into multiple *.md files and expanded
     in the docs/ directory.

0.5.5  2021-07-09T08:21:49+12:00
   - Implement reading of CMaps with variable encoding and
     CID mappings #9

0.5.4  2021-07-05T09:20:00+12:00
   - Add new sub-class PDF::Font::Loader::FontObj::CID
   - Fix ToUnicode CMaps for subsetted fonts
   - Allow subsetting of 'CFF' format OpenType fonts. HarfBuzz can
     handle these.

0.5.3  2021-06-30T11:20:17+12:00
   Glyph maps #8
   - Rename PDF::Font::Loader::Metrics -> PDF::Font::Loader::Glyph
     and shape() method to glyphs()
   - Handle unknown and un-mapped custom type-1 glyphs. Provide
     a glyphs(@cids) multi method to allow glyph extraction when
     there's no unicode mapping
   - Handle /CIDToGIDMap entries in font dictionaries

0.5.2  2021-06-26T09:58:42+12:00
   - Added PDF::Font::Loader::Metrics class and $font-obj.shape
     method.

0.5.1  2021-06-24T13:52:53+12:00
    Reusing a font within a PDF copies it #6
   - Accept :$dict option re-use it, updating as needed (char-maps,
     widths, encoding differences.
   - Renamed PDF::Font::Loader::FreeType -> PDF::Font::Loader::FontObj
   - Make font width tables authoritative; stringwidth() method now
     checks the font's width array (/W or /Widths entry) before
     consulting font metrics.
   - Add glyph-width() rw method
   - Fix font-name() and is-embedded() methods

0.5.0  2021-06-19T10:10:30+12:00
   More forgiving font handling #7
   - Added support for TrueType Collections, which must be embedded.
   - Change font validation to accept any FreeType font, but check
     basic characteristic are present, and only restrict embedding
     to permitted font formats.
   - Warn and disable embedding, rather that aborting, if the font
     doesn't meet embedding criteria.
   - Changed default option for loading from PDF dictionary :!embed
   - Defer some error checks until font object construction; to make
     reading of PDF files even more forgiving.
