The Tagtool universe is a Doughnut universe - imagine an ant on a Doughnut. If it goes right, it comes back from the left side, if it goes up, it comes up again from below.
So to make panoramic scenes:
Apply a horizontal scrolling motion to the whole scene
Draw a landscape or similar across the whole screen, release. It will take on the movement.
Keep drawing and releasing landscape segments until there are no gaps
