\r
86 Yes, I guess that is possible at some level.
\r
88 The fringe is a bitmap - we could use the leftmost vertical line of it
\r
89 for the outermost component, next line for the next component, ...
\r
91 Or perhaps use images:
\r
92 - all levels of the message at this line are "good",
\r
93 - some of the levels of the message at this line are "good".
\r
95 Or maybe display a QR code in the fringe, and you point your phone at it
\r
96 to find out what is going on?
