+# JavaScript polyfills
+
+This directory contains JavaScript "Polyfills" to support rendering of SVG 2
+features that are not well supported by browsers, but appeared in the 2016
+[specification](https://www.w3.org/TR/2016/CR-SVG2-20160915/pservers.html#MeshGradients)
+
+The included files are:
+ - `mesh.js` mesh gradients supporting bicubic meshes and mesh on strokes.
+ - `mesh_compressed.include` mesh.js minified and wrapped as a C++11 raw string literal.
+ - `hatch.js` hatch paint server supporting linear and absolute paths hatches
+ (relative paths are not fully supported)
+ - `hatch_tests` folder with tests used for `hatch.js` rendering
+
+## Details
+The coding standard used is [semistandard](https://github.com/Flet/semistandard),
+a more permissive (allows endrow semicolons) over the famous, open-source
+[standardjs](https://standardjs.com/).
+
+The minifier used for the compressed version is [JavaScript minifier](https://javascript-minifier.com/).
