1604 	/** This is the main interpreter method. It is designed to handle the given Metafile
1605 		completely inside the given context and target. It may use and modify the context and
1606 		target. This design allows to call itself recursively which adapted contexts and
1607 		targets as e.g. needed for the META_FLOATTRANSPARENT_ACTION where the content is expressed
1608 		as a metafile as sub-content.
1609 
1610 		This interpreter is as free of VCL functionality as possible. It uses VCL data classes
1611 		(else reading the data would not be possible), but e.g. does NOT use a local OutputDevice
1612 		as most other MetaFile interpreters/exporters do to hold and work with the current context.
1613 		This is necessary to be able to get away from the strong internal VCL-binding.
1614 
1615 		It tries to combine e.g. pixel and/or point actions and to stitch together single line primitives
1616 		where possible (which is not trivial with the possible line geometry definitions).
1617 
1618 		It tries to handle clipping no longer as Regions and spans of Rectangles, but as PolyPolygon
1619 		ClipRegions with (where possible) high precision by using the best possible data quality
1620 		from the Region. The Region is unavoidable as data container, but nowadays allows the transport
1621 		of Polygon-based clip regions. Where this is not used, a Polygon is constructed from the
1622 		Region ranges. All primitive clipping uses the MaskPrimitive2D with Polygon-based clipping.
1623 
1624 		I have marked the single MetaActions with:
1625 
1626 		SIMPLE, DONE:
1627 		Simple, e.g nothing to do or value setting in the context
1628

1636 		bugdocs)
