OutlineLayer is a layer that is used to display the grey figures commonly used for drag-selection, reshaping items, and so on. It can have shapes added to it, which are all drawn in outline in grey (by default -- the color can be changed). There is no concept of a display list or z-depth in this layer, as all shapes are drawn in exactly the same color.
Although currently it does not do so, this class will become optimized so that repaints of this layer do not require a repaint of backing layers.
