Painted

Blake described a painted tile like this:

Think about if I was rendering a 0/0/0 tile from postgis and there was only a small park in my data. It would probably collapse to nothing at 0/0/0 resolution so the entire tile would be empty. So the tile would be considered empty, but there was originally data below it so for pyramid rendering we want to know that you can’t just copy this tile from now on. Therefore painted says “hey! there was some data!"(edited)
