I've noticed some of the example files (like the welcome file) use double square brackets. These clearly have some function, but I can't find it in the documentation. What do they do?

With single brackets the shape adjustments are re-ordered into a standard order (translate - rotate - size - skew - reflection or TRSSF). With double brackets the shape adjustments are applied in exactly the order that you specify. The idea is that the TRSSF order is usually the order that people want and the single-bracket shape adjustments allow people to not have to think about the order.
