Just found the following at the first link:
All coordinates of features should be Spherical Mercator integers. To save bandwidth and disk space, they are calculated to be relative to tile boundaries: [0,0] represents lower right corner, and [/granularity/, /granularity/] represents upper right.
Regarding [0,0] is the "lower right" and [g,g] is the "upper right", where does the "left" come in? Typo, or really intended to be that way?
