documentation for imap kinda... bogus?

[Brian Behlendorf <br...@organic.com>]

http://www.apache.org/docs/mod_imap.html is pretty skimpy, and I notce that
for elements like "poly", "point", two sets of x,y coordinates are given, and
I don't see how that's accurate at all.  The tutorial at
http://hoohoo.ncsa.uiuc.edu/docs/tutorials/imagemapping.html is a fair 
amount better, we should probably either point to that or revise ours.  
Looks like Randy was the last one to touch it :)

And am I the only one really thrown off by the fact that circles are 
defined using the centerpoint and an edgepoint, instead of a centerpoint 
and a radius?  eek.
