ElevationProfile: Allow tolerance for LiDAR data only.

[Ursenstein]

Feature description

Hello Colleagues! I use the terrain elevation profile to create visualizations for cable routes. In version 3.36, I was able to use the tolerance function to represent the Lidar data I used in a "wider" manner, which led to a "nicer" result. However, in the new version 3.38, this is no longer possible, as increasing the tolerance now also affects the cross-section, thus distorting the results of the elevation profile.

It would be nice if there were a way to increase the tolerance only for the Lidar data or overwrite the tolerance for selected Layers.

Behaviour in 3.36 With a Tolerance set to 20m, the PointCloud data shows some actual trees/houses.

If i set the tolerance to 20m in 3.38, it affects lines and polygons aswell. So in order to display the cross section of my cable route i must not use the tolerance feature at all, what now makes displaying a wider range of point cloud data not possible. https://www.qgis.org/en/site/forusers/visualchangelog338/index.html#feature-add-tolerance-for-lines-and-polygons

I know that this is not an issue or a bug, rather a feature request to overwrite the tolerance for specific layers.

Could you illustrate the previous and current behavior of your issue ?

now also affects the cross-section, thus distorting the results of the elevation profile

Explain the issue and describe how it should be

FYI @benoitdm-oslandia -- any thoughts on this?

Hi @Ursenstein, can you post an illustration of the actual result (with the 3.38) please?
