[iTowns-dev] Vector (tiles) as background

This is a follow up of my experimentation about vector support.
First of all, I would like to thank Jeremy Gaillard, Augustin
Trancart, Pierre-Eric Pelloux-Prayer for their support. They give me
I was able to make some WFS call using the Pierre-Eric's branch
mobile_mapping_wip . I cannot make it work using a plane (itowns.Scene)
instead of a globe (towns.viewer.createSceneGlobe) . I tried to reproduce
the APIGlobe function addFeatureLayer (exposing the updateFeaturesAtNode in
itowns.processing) without success.
In the Jeremy 3d-tiles-refacto branch , we have support for SRS, which
is quite useful for local data. I didn't figure out if it is available on
the mobile_mapping_wip branch.
3d_tiles support is awesome! We really enjoy this feature and we hope to
see it in 2.0 release.
My next step would be to drape a simple vector feature on the ground. It
looks like a pretty famiiiar use case. Any hint is welcome!
