Given that `DOMMatrix` is, unsurprisingly, not supported in Node.js the `createMatrix` helper function in `src/display/pattern_helper.js` is most likely broken in Node.js environments. It will obviously try to fallback to the `DOMSVGFactory`, however that isn't intended for Node.js usage and errors will be thrown. Rather than trying to implement a `NodeSVGFactory`, this patch takes the easier route of just adding a `DOMMatrix` polyfill using: https://www.npmjs.com/package/dommatrix This isn't done only for simplicity, but it'll become necessary anyway since the `createMatrix` helper function is only temporary and will be removed in the future.
