just for the record, turning off javascript and/or java only prevents
the capturing of resolution and color depth in the above list.  the
others are all gathered from your IP, your User Agent string (your
browser sets this, although some browsers, not the major ones, let you
play with it), and the referral field which is an HTTP environment
variable extension (and some browsers, but not the major ones, will let
you block).
