You would call doPrepare() on the OMGraphicHandlerLayer (your
extended version of that class). The DemoLayer is a better example
of how you should model your layer, just look at the prepare() method
and follow the logic in there for managing a list, and creating the
list the first time around. You can manage your OMCircle coordinates
in a different method, and call doPrepare() in that thread. doPrepare
() launches a new thread to call prepare() and repaint().
