[OSM-dev] [GSoC] Data tile example site

[Ander Pijoan]

Hi! I have a big question:

Imagine I download one of the tiles and keep it in my hard drive or in
a cache or send it to a client to open it in a program. The tiles
bounding box or X,Y,Zoom values are not in it so it won't be able to
know where to place that tile.

I know that when asking for the tile I have those X,Y and Zoom values
so I can calculate its position but if it is not written anywhere in
the tile. I made some tests with Kothic's tiles allocated at
Osmonimski.ru and those tiles at least have their bounding box and
also their X,Y and Zoom values explicit in them.
