// QrView — a QR code of a text (a URL), dark modules on white with the
// four-module quiet zone, whatever the theme: phones read it best that way.
// Square: the code fills the smaller side, in whole pixels per module.
// Drawn as one texture, scaled without smoothing: a path per module was a
// draw call each, and a long link (the bug-report form with a gist link)
// overflowed the frame's GPU command memory, which aborts the app.
