+
+            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.
