This is a helper primitive which allows embedding of single 3D
primitives to the 2D primitive logic. It will get the scene it's
involved and thus the 3D transformation. With this information it
is able to provide 2D range data for a 3D primitive.
This primitive will not be visualized and decomposes to a yellow
2D rectangle to visualize that this should never be visualized
