Remarks

ILayerPosition is implemented by layers that wish to define their order when added to higher level components, like maps, when auto arrange is used.  The LayerWeight property defines the weight of the layer in the auto arrange order.   During auto arrange, the higher weight layers are added to the map first, which means they draw lower in the draw order.

Default weights for layers are these values:
Annotation layers=97
Points layers=98
Polyline layers=99
Polygon Layers=100
