Remarks
The order of the layers in the LayerCollection determines the stacking (z-order) used when rendering. For instance, the layer at index 1 is rendered on top of the layer at index 0. The order can be changed using the ChangeAnnotationPosition(ChangePositionMethod) method; this is because a LayerAnnotation derives from AnnotationUI.
