Description
OL-Cesium does not use the Cesium widget for historical reasons.
As a consequence the OLCesium class needs to reimplement many mechanism, sometimes not 1:1.
We should consider reimplementing the OLCesium class on top of https://cesium.com/learn/cesiumjs/ref-doc/CesiumWidget.html?classFilter=widge#resolutionScale .
