Point with altitude with ol-cesium

[remiHau]

Hi,

We are using ngx-openlayers with ol-cesium to display a 3D view. I have managed to display feature with altitude for all the geometry except the point because the point use the coordinate component while the other geometry use the collection-coordinates component.
The coordinate component has 2 input x and y.
The collection-coordinates has an array of coordinates.
So if I set an altitude as the 3rd value of my coordinate, it will be store for the collection of coordinate but not for the coordinate component.

I am going to do a merge request for fix it but I am wondering what is the best thing to do :

• Add a z-input to the coordinate component to avoid changes in other application
• Allow the use of collection-coordinates component in the point but i am not really sure that makes sense.
• Change the x and y input by a OlCoordinate input but that's a breaking change

What do you think?
