layerling 1.72.3

• Reference points: delete them all, and cards that behave: Marking the centre, corners or edge middles of a body leaves several points, and deleting them one by one was cumbersome. Delete all in a point card, and "Delete all reference points" in the right-click menu, take them all away in one step (it can be undone). The cards no longer move as a group: each is dragged away on its own, and the card you touched last stands in front, so a card can no longer end up behind another. A point whose card was never moved keeps the place the shared offset had before. Reported by @rondlh (#329).
• A wrapped shape is not wrapped a second time: "Wrap around a cylinder" could be repeated on a shape that was wrapped already, and the second wrapping gave a mesh of an unexpected size and shape. The card is not offered for a wrapped shape any more, and the AI tool answers that the shape is wrapped already; undo the wrapping, or wrap the flat original again. Reported by @rondlh (#329).
• The edge tool names chamfer and fillet in your language in its messages: "Select one solid to chamfer" and "Preparing fillet edges" got the word as a raw English identifier in every language, so a German message read "Wähle einen Körper für chamfer". They take the name of the tool as the interface spells it now. Pointed out by @cyryllo in the Polish translation (#307).
• Zooming into the sky no longer tips the view down near the back edge: The camera that now goes on forward when the pointer is on the background (1.72.2) kept the pivot inside the plate by cutting each coordinate to the plate in turn. Near the back edge that turned the line of sight: the camera looked steeply down. The distance is now cut short along the line of sight, so the view keeps its direction. Reported in the forum.
• Shared folder: what the README had left out (#301): With Docker, the shared folder showed on the start page but nothing could be saved in it, because the container runs as the user 999 and a mounted folder is usually owned by somebody else. The README and compose.yml now say so (chown 999:999, or run the container as yourself with user:). With npm run start they now say that npm run build comes first and that the folder must be writable by the user who starts it. Reported by @foofoodog.
• Turn a selection in the sketch by any angle: The sketch could turn only a whole closed outline, 45 degrees at a time with R, so a single line, a curve, several outlines together or an angle in between could not be turned at all. A round handle now stands above the frame round a selection: dragging it turns everything selected - points, lines and curve handles - about the middle of the selection, with the angle shown over the handle, and with Shift in steps of 15 degrees. R still turns a closed outline by 45 degrees; the guide now says so in the text, not only in the table of keys. Asked for by @lukyanenkomax (#330), and earlier in the forum and by @strelniece (#260).
