Scan is done outside the selected area when the probe (laser point) offset is set

[bboilot-ledger]

To reproduce

1. Start laserstudio
2. Setup the probe offset (click on a bout different from the blue camera center)
3. In the stage setting, select positioning from laser/probe instead of camera
4. Select a zone to scan
5. Go to next position

Expected behavior

The scanning is done in the area considering only the probe position (so the probe offset is taken into account). The camera center can be outside of the area depending on the offset.

Current behavior

The offset seems to be added/subtracted two time. Result is that the scanning can be completely done outside of the zone, especially when such area is samller than the probe offset.
