It's all specified in the HTML specifications: http://www.w3.org/TR/html4/struct/objects.html#h-13.6. Rectangles are determined by just two points, and pair of opposing corners, so four numbers make sense for that. More specifically: for rectangles it's left-x, top-y, right-x, bottom-y; for circles it's center-x, center-y, radius; and for polygons it's just the x, y coordinates of each point in turn. All coordinates are relative to the top left pixel, which is 0, 0.
That's wonderful; I'm glad we have a clear specification document with which to...ah, but it's implemented? Hm.
That someone had to ask how to use the feature indicates that we need much clearer documentation, perhaps with a tutorial and a few nice diagrams.
Volunteers?
