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?
