I've run into a case where we need to change our crossOriginPolicy to "Anonymous" for a few tiledImages, leaving "use-credentials" as the default. TiledImages have support in the property declaration for crossOriginPolicy to be set individually, but when we add them through addTiledImage, that value is always inherited from the viewer. In getTileSourceImplementation, there is some code that checks for and sets crossOriginPolicy on the tileSource object that is passed in, but that value never makes it into the tiledImage that is added (it's passed into the TileSource constructor, which doesn't seem to have crossOriginPolicy as a property, so it gets lost). Was the idea to support setting crossOriginPolicy for a tiledImage through the tileSource? What is the best way to implement that feature?
