Duh, of course its not! Blame lack of caffine!
But as Marcalo says you should have a lat/long to tile conversion, so
just implement the function in lat/long space and use the conversion.
Probably put the zoom as the outer loop, and the vary the 'step' of
the lat/long loops depending on zoom level. (or just put the step
really small, and check if you done that tile already and skip it)
