+ /** MetafilePrimitive2D class
+
+ This is the MetaFile representing primitive. It's geometry is defined
+ by MetaFileTransform. The content (defined by MetaFile) will be scaled
+ to the geometric definition by using PrefMapMode and PrefSize of the
+ Metafile.
+
+ It has shown that this not always guarantees that all Metafile content
+ is inside the geometric definition, but this primitive defines that this
+ is the case to allow a getB2DRange implementation. If it cannot be
+ guaranteed that the Metafile is inside the geometric definition, it should
+ be embedded to a MaskPrimitive2D.
+
+ This primitive has no decomposition yet, so when not supported by a renderer,
+ it will not be visualized.
+
+ In the future, a decomposition implementation would be appreciated and would
+ have many advantages; Metafile would no longer have to be rendered by
+ sub-systems and a standard way for converting Metafiles would exist.
