Entity: Assign an offset to path of a model

[tkazik]

1. A concise explanation of the problem you're experiencing.

I have a model that has its reference frame not exactly in the center of the model.

I would also like to display the path of the model, which ideally should be in the center of the model. Thus, I would like to apply an offset transform to the path or model. 

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

        var entity = viewer.entities.add({

         position: W_t_W_M__sample,

                orientation: q_W_M__sample,

                model: {

                    uri: resource,

                    shadows: Cesium.ShadowMode.ENABLED, 

                },

                availability: new Cesium.TimeIntervalCollection([new Cesium.TimeInterval({

                    start: start,

                    stop: stop

                })]),

                path: {

                    resolution: 1,

                    material: new Cesium.PolylineGlowMaterialProperty({

                        glowPower: 0.1,

                        color: Cesium.Color.YELLOW

                    }),

                    width: 10,

// possibility to add some sort of offset?

                }

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

There are two option:

1. Having some sort of offset in an entity would be nice

2. Adding another entity with a new sample position just for the path

For the second option: How could I have two entities running both at the same time?

4. The Cesium version you're using, your operating system and browser.
