Only use the amount of memory needed in sharedbuffergeometry based on networked-drawing configuration. Only create a sharedbuffergeometry object when a pen is first spawned.
Also, reduce the amount of memory used by primitive entities (cursor, spawned pens, teleport-controls)

fix bug that occur because clients were assuming mutual dataChannel connections when that is not always true (client B can't assume it can message client A even if it has received a message from client A already)

fix issue with pen not drawing until second primary_grab; fix spawn_pen-hover icon; enable spawning pen from in-world-hud; re-enable personal space bubble as default

add ability to spawn pen from hud (replacing the space bubble toggle); disable space-bubble as default

various updates to support moving the duck and pen into the gltf-component data of the environments instead of hubs.html and getting rid of interactable-template again

allow changing color and scale via mouse when holding alt or shift keys; fixing/changing input for rift.

instead, pulse when grabbing and releasing. Also enable haptics for the cursor.

fixed faceculling order on geometry for lines and caps, both even and odd segments. Added timed delete per line. Fixed networking bug where line data could be sent before remote clients were fully initialized. Adding drawing manager that prevents multiple pens from drawing on the same drawing at the same time.

This isn't relevant now given the cleaned-up client deploy process.
