eulerr (version 8.1.0)

build_tag_grobs: Build the leader / label / quantity / annotation gList for one tag.

Description

Shared between setup_tag() (initial construction in setup_grobs()) and makeContent.EulerTags() (draw-time re-placement on resize). Pure factory — no measurement; takes anchor + tether already in native units, plus the stashed text / gpar bundle. The label / quantity / annotation stack is centered vertically on (ax, ay) so the bbox center matches the anchor eunoia placed and leader endpoints land on the actual bbox edge.
