per-feature: the same elevation offset is applied to the entire feature.
Suitable for level geometries, such as buildings, lakes, etc.
per-vertex: the elevation is applied to each vertex independently. Suitable for
lines that must follow the terrain, such as roads.
none: no draping is done, the elevation of the feature is used as is. Suitable for
geometries that should not be draped on the terrain, such as flight paths or flying objects,
or for 3D geometries that already have a vertical elevation.
Note: that Point geometries, having only one coordinate, will automatically use the per-feature mode.
