8106fccdd27527ef4fe93b9241a55eeae141977e
libremetaverse/OpenMetaverse/ObjectManager.cs
John Hurliman 8106fccdd2 * Changed Primitive.TextureEntry.ToBytes() to GetBytes() to follow naming conventions 
* Added Primitive.TreeSpecies and Primitive.ScratchPad
* Converted Primitive.SoundFlags to the new SoundFlags enum
* Added a Utils.BytesToString() overload that accepts index and count parameters
* Added Utils.FloatToUInt16()
[Simian]
* Lots of changes in Simian to use the new unified ISceneProvider.ObjectAddOrUpdate() function
* Update flags are checked to determine the minimum sized packet that needs to be sent out for an update. ImprovedTerseObjectUpdate is working, and started work on ObjectUpdateCached (updates using this will currently not send)
* Adding three new variables to SimulationObject to store attachment-related state
