For a 9999-point tracklog, the tileserver approach takes about 140 ms
per tile to render.  When it needs to download a tracklog that it's
never seen before, that takes about 800ms.  Tiles that don't intersect
with the tracklog bounding box (completely transparent ones) take
3-4ms.

Timings measured using microtime() from within the PHP tile server.
