Hi Carsten, Now I understand. It was quite strange for me to see such a discontinuity on negative values, where my idea was only to move the overlay around in the viewport with an offset... :-) I'll have to implement it considering that...
Regarding the variations of negative and relative/absolute coords, it seems they are correct.
