See how to move the label position with a delta from the reference point.

| c ptA|
c := DrGeoCanvas new.
ptA := c point: 0@0.
ptA costume computeTextPositionDelta: 25@ -25.

Use the #constraintTextPosition: message to provide coordinates position, but it is tricky to use at it requires pixel position.
