Jake,
I cannot use bitmapdata because i'll have to use an instance of itemrenderer
which will have some different display behavior when used as proxy.
I've managed to get a transparent bg, I had to set explicitly in css class
applied to the *list* (because proxied itemrenderer use
"styleName=List(owner);") :
> background-color: '';
>
BTW, "selection-color" set to empty string draws a black bg...
