If I'm understanding Z-order... if you put an element "behind" another element by having it drawn first, both visually and functionally the element is onto of the other element. Is there a way to visually put something ontop another element so it draws first, but put the functionality of the underneath element as on top of the first drawn element?
This basically allows me to create some really sophisticated variable driven images without have to create 30 different images. I can basically get away with what I need with 13 images.
