z-index overhaul. relative above static; negative z-index
1. when stacking without z-index, positioned > floated > normal flow 2. supports negative z-index 3. new stacking context formed when opacity < 1 (standard) 4. new stacking context formed for position:fixed (no standard yet, done in mobile webkit and chrome 22+)
