Returns the position of this NetElementGeometry in the global
coordinate system of the host of its owner (that is, the graph space
coordinates for an inner block).
The returned transform matrix can be used to transform the local
coordinates of any point contained in this NetElementGeometry into
the coordinates system of the host of its owner.
Constructs a new NetElementGeometry at the given position in the
relative coordinate system of the host of this NetElement with
width and height being 0.
