There is another option: instead of using OsmaRender to render
images, ""render"" a text file that can be interpreted as a OpenLayers marker
layer. In fact, we should only need such a file per level 12 tile.
The computing time (and output files) for such a task should be small enough
to not be a problem, and it would provide the needed flexibility.
The problem here would be dinamically loading files with markers depending on
the level-12 tile we're in, and not showing anything in lower levels. Sounds
like we can have lots of fun hacking OpenLayers...
