1st part of syncing bundled LibGd to ext/gd/libgd # Updated/Fixed - Color Match improvement using Lab* + Delta-E and actual % as input - Fix and improve freetype rendering and merge both php's libgd + libgd "new encoding" - Fix RAMQ rendering - All codecs with conformance tests (upstream, C) - Perceptual difference (upstream C, will be exposed so php's tests can rely on it - libgd codecs include gif, bmp, webp and jxl full support including animation. Tiff read/write multipages. all BMP format supported but OS/2. Many of these additions or changes work already with existing php's apis. 2D vector APIs and all new Codecs or Gd\* APIs will be a separe PR+RFC. See https://wiki.php.net/rfc/ext-gd-2.4
