Does anyone know what these new handles are supposed to do?
I checked and they were not in pre-1.x versions. I don’t recall seeing them on early 1.0 versions. They look like the universal symbol for crop, but I can’t get them to do anything. They appear on a third click after the usual scale and skew/rotate handles. Also on regular objects and paths, as well as imported bitmaps.
Nothing I can find in docs, or searching Inkscape community.
