mergAV uses GLOBAL coordinates?

Hi Brian,

I now have the proof that mergAV DOES in fact needs global coordinates.
Thanks for that, Matthias!

This (as found in the dictionary) gives you the offset:
mergAVCamSet "rect",the rect of graphic "qr_ios"

However THIS is neccessary to make it work correctly:
put the topleft of grc "qr_ios" into tRect1
put the bottomright of grc "qr_ios" into tRect2
put globalloc((tRect1)) & "," && globalloc((tRect2)) into tRect
mergAVCamSet "rect",tRect

I really wonder why noone noticed this before!?

Will create a bug report for thhis later this evening.
