Missing check for CORS for WMS layers

[gioman]

The result of adding a WMS from a server with no CORS is that the application returns the error:

There was an error loading tiles.

The necessity of CORS on the server side must also be documented (as also for WFS, there is a separate ticket for that) @SrNetoChan

I am no expert on that, but why do you need the CORS check for WMS? We are checking it for WMS layers, only if there is a popup for that layer, since that makes sense, but otherwise, i guess it is not needed, right?

@bartvde?

Anyway, if it has to be done, i can do it easily

CORS is needed otherwise we cannot print or export to PNG

CORS is needed otherwise we cannot print or export to PNG

is not also the reason behind the "There was an error loading tiles" error?

@gioman just to be sure, can you attach an app that shows this?
