Stephan Sokolow 2a8f852c68 Ensure QR codes have a border large enough for successful scan
(The QR code spec requires a border at least 4*box_size thick but we can't
 just set border=16 because that results in a QR code more than 255px tall
 and I'm not yet ready to use fullimage() as a backend for it)
