+ target. This design allows to call itself recursively which adapted contexts and
+ targets as e.g. needed for the MetaActionType::FLOATTRANSPARENT where the content is expressed
+ as a metafile as sub-content.
+
+ This interpreter is as free of VCL functionality as possible. It uses VCL data classes
+ (else reading the data would not be possible), but e.g. does NOT use a local OutputDevice
+ as most other MetaFile interpreters/exporters do to hold and work with the current context.
+ This is necessary to be able to get away from the strong internal VCL-binding.
+
+ It tries to combine e.g. pixel and/or point actions and to stitch together single line primitives
+ where possible (which is not trivial with the possible line geometry definitions).
+
+ It tries to handle clipping no longer as Regions and spans of Rectangles, but as PolyPolygon
+ ClipRegions with (where possible) high precision by using the best possible data quality
+ from the Region. The vcl::Region is unavoidable as data container, but nowadays allows the transport
+ of Polygon-based clip regions. Where this is not used, a Polygon is constructed from the
+ vcl::Region ranges. All primitive clipping uses the MaskPrimitive2D with Polygon-based clipping.

+ Simple, e.g nothing to do or value setting in the context
