"grey not in cache" and "red tiles" WMS Plugin

If you work on bigger areas, you sometimes get a problem with red and grey tiles. There is only the option "download erroneous tiles" but it doesn't make differences between grey and red tiles.

The issue is that some provider of WMS-Pictures (e.g. PCN in Italy, who explictly permitted use for OSM, see Wiki) limit the download area/size as anti-leaching measure. Getting a new IP helps ;-), but if you download all erroreous tiles, you will again be instantly blocked if you already worked a lot after the block (=lots of grey tiles).

I have several ideas how this could become better:

  • talk to PCN (we did and keep on)
  • offer a second option: download all previously red tiles, and grey tiles separately
  • offer explicit download of single tiles by rightclick in the main edit window (download tile)
  • try to download grey tiles (offlinemode) again automatically when switching to "automatic downloading" or (similar) delete all "not in cache"-tile-markers when switching to "automatic downloading"

See #5207 - grey tiles are now downloaded with automatic mode as well as when choosing "download visible tiles".
