/** 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 existung, 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.
