I'll blow the whistle on this....
|----| | | Image 1...on main screen | | |----|offset of magnifiying glass is constructed from the top and left of the graphic on the stage.|--------| | | Image 2 in miaw, but only top corner is visible. | | | | | | |--------|
the registration point of image 2 is set at 0,0
image 2 is 2x the size of image 1.
therefore you move to image2, you set the locs of the image2 = -1*(2*the offset value for each h and v)..
