Element z order is relative to the element collection within their parent. The bottom element has a z order of 0. The top element has a z order of N - 1. If the element is already at the bottom of its parent's element collection, false is returned. False can also be returned if the element's z order cannot be checked (i.e. the element is not a graphic element, a group element, does not belong to the graphics layer, etc.).
The map view displaying the graphics layer should be initialized.
