Ack. My original suggestion was focused on 0=disable, >0 is scale. I
literally pulled the name from my nether-regions. :-)

The real text is still sent to the (hopefully written to disk) logs. If
a user (or distro) builds with this feature, I would think centered and
scaled for ease of scanning would be highest priority.

I don't think there is a 'safe' part of the framebuffer real estate
where the QR could be written for all scenarios. Best to make it easy
to scan.

thx,

Jason.
