+ * "layer". It is typically directly placed in the <svg> element but it is also possible to put
+ * inside any other layer (a "layer" inside a normal group is considered a group). The GUI tracks
+ * which is the "Current" layer. The "Current" layer is set when a new selection initiated
+ * (i.e. when not adding objects to a previous selection), when it is chosen in the "Layers and
+ * Objects" dialog, when using the previous/next layer menu items, and when moving objects to
+ * adjacent layers.
