Issues with Instancing

[Ilwyd]

Using this to keep track of issues found while experimenting with pre-existing instance code:

• Overlay and Underlays are not present in the instanced area
• Ground height data is not copied over
• Objects flicker often while moving around the instance
  • Seems to be related to Chunk.sendUpdates. I think this runs every time the player moves.
  • Increasing the height value passed to UpdateZoneFullFollowsMessage results in 2 versions of the instance appearing where only the version with the higher height flickers (video 1)
  • The non-flickering version is created by UpdateZonePartialFollowsMessage
• Teleing to the instance area after creating it results in a black screen. Does not happen when already in the instance area. (video 2)
  • Teleing out of the black screen results in the UpdateZoneFullFollowsMessage version of the instance appearing wherever you arrive
  • Related to RebuildRegionMessage.
    • Encoder and Message classes already exist
    • We don't currently have a packet structure defined for this.
