[flexcoders] tilelist HighlightIndicator effects

[stinasius]

hi i would like to define fade or move (or a combination of both)
effects for a tilelist's HighlightIndicator so that instead of just
appearing or disappearing it moves and fades in when mouse is over an
item in tile list and moves and fades out smoothly when mouse roll's
out and is over another item. hope am not being extravagant with this.
is this possible and if it is, how? thanks
