A couple ofyears ago it seems I asked Anobium what happens when you draw a box say so it goes off screen ie it's end co-ords are greater than the screen size.
I posted some programs showing the effect on different glcds and it depends,,,it seems.
The first solution was modify the draw code and when it gets to pset check
if off top of screen make it bottom and same for bottom and left and right but that would slow the draw code a lot.
Think of the old asteroids game and how the rocks wrapped around the edges of the screen to the opposite edge.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
