Well, not exactly. We have some larger images that we want to always
stay behind the smaller images even when the larger images are dragged.
Actually, I was able to do it by making two Drag objects and making the
start zIndex an argument of the Drag constructor (new Drag(zIndex)).
This allows me to have one Drag that exists, say over 200 and another
which exists at 100.
drag1=new Drag(200)
drag2=new Drag(100)
Then I made it such that a given drag object can alert another drag
object if its zIndex goes above 100 plus its set zIndex, it will shift
the alerted drag up 100. (So if you click on the background images and
they move towards the zIndeces of drag1, then drag1's zIndeces will be
moved up 100 to ensure that they stay in front.
drag2.setAlert(drag1)
When it is up I can post it to this list as an example.
