PB-2234: disable custom Cesium post-processing

[pakb]

What was working with previous version of Cesium is now creating rendering artifacts with our terrain (see ticket https://swissgeoplatform.atlassian.net/browse/HDG-43 )

Disabling all post-processing is removing all these artifacts, and it also should render things a bit faster

I tried multiple times to zoom in on the landscape to see if the artifacts are still visible or not, but every time after some zooming i got this error, if i remember correctly we had this once before, maybe thats why we added the post-processing?

I tried to pin-point if this error was linked to the same issue, but it doesn't look like so. It is linked to the label layer that isn't behaving well within the newer Cesium engine.
If you zoom in too quickly it kind of breaks the engine. (and if you disable labels and zoom in quickly, nothing breaks)

ok thanks for clarification, it might make sense to add a comment of this break to the label layer, also maybe add a coment to the CesiumMap.vue to explain why post processing is not added, so in the future we do not add it back again and have the same issue again

I got a different error, but most probably it's not related

[pakb]

As discussed, this won't fix the error that pops up when the label are screwing the Cesium engine, only the artifacts on the terrain.
We'll see if we can live with this label creating error on production or we will need to do something about it later

I don't see the stripe in the test link 👍
