Interesting! Looking at some of the remaining examples, I found the use of the transform attribute, and also, the use of the <svg> element as a grouping unit, although it looks like it’s added ‘under the hood’ to group the visible element with the manipulation hotspots. There might be a way of, or example for, expressly using a grouping like this in the code for the scenegraph node transformations I’m seeking. Then some kind of SVG output is needed which cleanse the interactive SVG from the hotspots and the <svg> groupings that only exist for grouping the visible glyph with the hotspots.
