Shared Drawables Test
[OVERVIEW] Tests the performance of linked objects and linked attachments
[SETUP] Requirements: 1 User, Rezzable area
 Make sure linked objects don't blink out of existence, change lighting, or look different in any way when they start moving and stop moving for a few seconds.
 Make a linked object with a script on it that makes it move continually (spin in a circle) then perform the following actions:
 Zoom in on a child object, the camera should not go "wonky"
 Edit a child object without unlinking the group
 Sit on a child object
 Attach text to a child object
 Perform the above actions on attachment. Note that certain operations (zooming in) do not work the same on attached objects or are not possible (sitting).
