Adds an
int ZIndexproperty toIView.The Controls implementation defaults it to zero. The z-index is honored in the layout handlers - items with a higher z-index are drawn above items with a lower z-index. The ordering happens in the handler/native view layer - the order of items in the Core layouts is preserved.
If the z-index is unused, the original behavior (items are drawn in the order they are added to the layout) is preserved.
Z-indexes can be negative, and will behave accordingly (lower values will be draw below higher values). When z-indexes of elements are equal, they will be drawn in the order they were added to the layout.
This only affects the ordering of the elements in the layouts; this implementation does not map to any native properties (e.g., Elevation on Android or CALayer.zorder on iOS). Alternate handler mappings can use those properties if desired.
