/**
 * Build a QR code to embed in a PDF.
 *
 * Note that pdfmake directly supports building QR codes, but we aren't using
 * it. The reason for that is that it sizes the QR codes based on a whole-number
 * value for the module size, where a module represents an on or off square in
 * the QR code. Because of this, QR codes rendered directly by pdfmake cannot
 * scale arbitrarily, but instead jump between sizes depending on what it
 * calculates for the module size based on the `fit` option:
 *
 * https://github.com/bpampuch/pdfmake/blob/b38e439e66a60c21d23d251311c636ed5d4ce7ad/src/qrEnc.js#L749
 *
 * Instead, we generate an SVG and use pdfmake's SVG support to render the QR
 * code, which allows us to scale it as we see fit.
