/** MediaPrimitive2D 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 definiton 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.
