BUNDLED THIRD-PARTY SOFTWARE A. opentype.js 1.3.4 Purpose: writing OpenType font outlines and tables. Copyright (c) 2020 Frederik De Bleser; project contributors. Licence: MIT. https://github.com/opentypejs/opentype.js https://github.com/opentypejs/opentype.js/blob/v1.3.4/LICENSE B. tiny-inflate, bundled inside opentype.js Purpose: font library's WOFF decompression support; the application itself uses opentype.js to export rather than upload external font files. Copyright (c) 2015-present Devon Govett. Licence: MIT. Port of Joergen Ibsen's tiny inflate; this ancestry is acknowledged by upstream. https://github.com/foliojs/tiny-inflate https://bitbucket.org/jibsen/tinf C. String.prototype.codePointAt polyfill, bundled inside opentype.js Purpose: Unicode code-point compatibility support. Author: Mathias Bynens. Bundled upstream code identifies itself as v0.2.0. Licence: MIT. https://github.com/mathiasbynens/String.prototype.codePointAt D. Clipper / clipper-lib 6.4.2, JavaScript port 6.4.2.2 Purpose: combining contours and generating outline thickness. Original Clipper: Angus Johnson, copyright 2010–2017. JavaScript translation: Timo, as credited by the bundled source. Licence: Boost Software License 1.0. Distribution repository: https://github.com/junmer/clipper-lib Original project: https://sourceforge.net/projects/polyclipping/ JavaScript project: https://sourceforge.net/projects/jsclipper/ E. JSBN subset bundled inside JavaScript Clipper Purpose: large-integer arithmetic used by the geometry library. Copyright (c) 2003–2005 Tom Wu. Clipper's header also identifies 2005. Licence: Tom Wu's permissive JSBN licence; retained verbatim in the notices. http://www-cs-students.stanford.edu/~tjw/jsbn/ Clipper's source header additionally acknowledges these technical references: - Bala Vatti, “A generic solution to polygon clipping,” Communications of the ACM, Volume 35, Issue 7, July 1992, pp. 56–63. - Max K. Agoston, Computer Graphics and Geometric Modeling: Implementation and Algorithms (Springer, 2005). - “Polygon Offsetting by Computing Winding Numbers,” ASME DETC2005-85513. These are upstream scholarly references, not additional copied applications. Their original links remain in the bundled header. 3. ARTWORK, UI AND DESIGN REFERENCES Implementation assistance: OpenAI ChatGPT/Codex, used under Anton's direction. OpenAI is not represented as an endorser or as an additional software dependency. ================================================================================ LIQUITYPE — THIRD-PARTY NOTICES Bundled font exporter: opentype.js The MIT License (MIT) Copyright (c) 2020 Frederik De Bleser Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
