Incorrect coordinates in demo

[osjonathan]

Looking in the mapbook.xml for the demo, I see:

<param name="max_extent">-20037508.342789,-20037508.342789,20037508.342789,20037508.342789</param>
<param name="initial_extent">-10384069.859924,5538318.529767,-10356632.423788,5563580.927174</param>

I'm guessing the parameters are supposed to be minX, minY, maxX, maxY
However, if you look at max_extent, you'll see that the first two coords are both identical, as are the last two. It still seems to work of course, so no idea what it does.

Web Mercator is square, it is minx,miny,maxx,maxy.

That doesn't explain why for max_extent the minx and miny coordinates are identical, as are the maxx and maxy.
