 Some notes about filtering:

  - Invalid index values or out of bounds indexes will end in `Invalid layer filtering` errors.
-  - Once a Mapnik layer is selected, all Mapnik layers will get blended. As this may change in the future **it is
-  recommended** to always select all Mapnik layers if you want to select at least one so you will get a consistent
-  behavior in the future.
  - Ordering is not considered. So right now filtering layers 0,3,4 is the very same thing as filtering 3,4,0. As this
  may change in the future **it is recommended** to always select the layers in ascending order so you will get a
  consistent behavior in the future.
