that do not have that type of data
- fix some regression shapes that had "empty" uv values
(including some minor topo surgery that luckily appears to not break

- fix Hbr to correctly pass the hole tag from parent to child face
- fix FarSubdivisionTables to handle disconnected face-vertices without crashing
