I think there's a "Copy Image" menu in there somewhere. Or was. The LayerViewPanel's RenderingManager maintains several transparent images (one for each layer, then one for the yellow selection handles, and maybe a couple more). So you could add another image ("Renderable" I think they're called), or do it manually using the same technique.
Or you could adopt the strategy that several CursorTools use and simply draw your lines in XOR.
