WM_position2element()
Author: Taylor
Author Email: taylor@wired.com
Author URL: http://www.taylor.org/
URL: http://www.hotwired.com/webmonkey/code_library/dhtml/wm_position2element/
This action positions one DHTML element a specified number of 
pixels away from another, based on the left, top, right, or 
bottom of the bounding box of each element. To use it, you must 
choose the element to position and the element to position against;
specify which side of each element's bounding box to base the 
positioning on; and supply the number of pixels difference between 
the two. Optionally, you can choose the browser window as the 
element to position against by using the string "window".

You can only position either the left or the top of an element 
on each function call, not both at once, so multiple calls will 
be necessary if you want to offset the positioned element in two 
dimensions at once. This also only updates the element once, so 
if you want elements to follow each other in formation you'll 
need to call the function multiple times.

Usage: WM_position2element(elementPositioned, 
left|top|right|bottom, differenceInPixels, 
elementPositionedAgainst|window, left|top|right|bottom);
