Updated to version v101.

Download QR-Reader_v101 from "Sample Stacks" of the LC toolbar or
http://livecodeshare.runrev.com/stack/943/

The stack works now also on linux with snapshots from the browser widget or
other apps on screen using a lengthy but clever workaround by Mark Wieder
(see bug # 20104). Dragging images from apps outside LC works now also on Win.

Note. On linux use http://forums.livecode.com/viewtopic.php?p=153351#p153351
to have the browser widget run on LC 8/9 with Ubuntu 1604 (64bit).

In sum, the QR-Reader helpers besides snapshots work now with images
("nots" are LC bugs) in the sample stack as follows.

Mac: CA, CB, DA. But not DB.
Win: CA, DA. But not CB and DB.
linux: CA. But not DA, CB and DB.

CA = Copy/Paste from other apps
CB = Copy/Paste from browser widget (rightClick)
DA = Drag from other apps
DB = Drag from browser widget
