I agree, that looks ugly as hell.

Sure, I made the regexp recognize negative numbers as well, so the error tiles are gone. We have now black tiles above and to the right of the map, as those are send back for "invalid" coordinates (too big/small x,y,z). However that is totally configurable what we send back in that case, would you prefer a completely transparent tile? Should it continue to be black? Shouldn't we send back anything at all but rather reply with a standard 404 not found?

I'm open for suggestions on this one.
