mergAV uses GLOBAL coordinates?

[Mike Kerner]

just checking into this thread, for the first time.
you already figured out the important part: it uses global coords.
the example code that i have includes taking that into account. it's
actually part of a larger routine that sets all the mergav props for
barcode scanning.
