[qgis-qwc2] How to enable backgrounds in printouts of demo-app?

[Roman Meier]

Hi Sandro,

I struggled to grasp the concept behind the "double" configuration in
themes and project.

"osm_farbig" isn't actually a valid qgis-Layer. Therefore it's resulting
in an error message when trying to print.

Since I can't modify the project file myself, I simply linked "mapnik" to
the existing qgis layer "Stadt- und Ortsteilgrenzen".

        "backgroundLayers": [
          {
            "name": "mapnik",
            "printLayer": "Stadt- und Ortsteilgrenzen",
            "visibility": true
          }
        ],

Now, anytime "mapnik" (Open Street Map) is selected "Stadt- und
Ortsteilgrenzen" shows.

Works like a charm!

Thanks!
Roman
