feat(SideBarWidget) add 3DTiles loading feedbacks

[valentinMachado]

Add feebacks of the 3DTiles loading (an ui element and some box3 in the scene)

Depends of this PR

[valentinMachado]

in order to test this feature you could have to remove the loading screen

Indeed, loading screen needs to be removed to visualize this feature.

It seems that the UI element disappears when one tile has been loaded in the scene, should it not wait for all tiles to be loaded before disappearing?
Also, I could not see the 3D elements in the scene that show a tile loading (from what I understand, it should be a cube that uses the bounding box of the tile being loaded)

Does Itowns wait for a tile to be loaded before requesting another ? If not, should we not display multiple 3D object for each loading tile ?

I've created a dedicated example to visualize this feature

yes if there is still one tile which has been requested and not loaded the ui element should remains, this is working on my camputed though

yes that's the behavior expected also working on my computer though

No tiles are requested simultaneously depending of the culling test function

If not, should we not display multiple 3D object for each loading tile ?

That's should be the case...

Have you run an npm i to update with the last itowns version ? If yes could you try to reproduce behaviors you are describing with the new example

[clementcolin]

Yay, it works fine now :) I do not understand how it worked before without the event.tile_requested though.
