The contentIDToLowRendererFactoryMap contains renderers that paint below the layers e.g. gridlines.
The contentIDToHighRendererFactoryMap contains renderers that pain above the layers e.g. scale bar, selection handles, etc. This code just grabs the renderer from one collection or the other and returns it. For example, if contentID is SELECTION_HANDLES, it will return the renderer for selection handles (from the second collection).
