annotate widgets/LayerTree.h @ 1457:160e6d010141 single-point

Avoid showing progress bars for dormant layers. They'll typically be duplicates, e.g. in the vect app you can get many dormant layers all reporting the alignment completion at the same time. (Maybe it would be better just to reject progress bars for alignment in dormant layers? Hm)
