// Note from the Scriptographer.org Team

// In Scriptographer 2.9, we switched to a top-down coordinate system and
// degrees for angle units as an easier alternative to radians.
// 
// For backward compatibility we offer the possibility to still use the old
// bottom-up coordinate system and radians for angle units, by setting the two
// values bellow. Read more about this transition on our website:
