[Feature Request] How to edit vc-drawing (manually add/edit/remove nodes) => save drawing/export/load

[romain974]

Existing Component

Yes

Component Name

vc-drawing

Description

I use vc-drawing, but need some interaction: I wan't to allow my users to save their drawing to geojson, and upload geojson to be able to modify.
I'm unable to find how to do this. Any clues ? Seems faisible, but i reaaly don't undestand how the drawing component works (no datasource?).
Any help would be appreciated, and I can in return push my code to help improve vue-cesium.

In terms of editing, obtain the renderDatas for each drawing component, and exporting involves exporting this array as well. Please refer to #435
