...mostly done with a rewriting Clang plugin, with just some manual tweaking necessary to fix poor macro usage. Change-Id: I71fa20213e86be10de332ece0aa273239df7b61a

/** 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.
