Detailed Description

TransformPrimitive2D class.

This is one of the basic grouping primitives and it provides embedding a sequence of primitives (a geometry) into a transformation. All renderers have to handle this, usually by building a current transformation stack (linear combination) and applying this to all to-be-rendered geometry. If not handling this, the output will be mostly wrong since this primitive is widely used.

It does transform by embedding an existing geometry into a transformation as Child-content. This allows re-usage of the refcounted Uno-Api primitives and their existing, buffered decompositions.

It could e.g. be used to show a single object geometry in 1000 different, transformed states without the need to create those thousand primitive contents.
