Transformed objects are implemented in Pattern

[kirchner]

Objects should be transformable. For example, one should be able to mirror an existing point along an axis, creating a new point. This includes implementing the following functions

• Pattern.insertTransformation
• Pattern.transformedObjects
• Pattern.transformedPoint
• Pattern.transformedAxis
• Pattern.transformedCircle
• Pattern.transformedCurve

as well as handling the NotComputableYet-cases in the following functions

• Pattern.computePoint2d
• Pattern.computeAxis2d
• Pattern.computeCircle2d
• Pattern.computeCurve2d
