Usage: put this tag anywhere in the of an HTML page:
Note that this will result in a one by one invisible pixel, so if it causes
misalignment in the page, it can be placed at the very bottom (before ),
or anywhere else where it will really be invisible.
Set doTagging to "true" to switch from screen info to page tagging.
