This is usually because the file name was singular (*Service*) but the class name was plural (*Services*).
This is to make configuration easier rather than having to look in the c# code itself to find the slightly different name of the connector.
This does not affect existing configuration since the files are being renamed rather than the classes.
This is not used for anything - appearances are always properties of objects with ids (ScenePresence, AgentCircuitData) and just has the potential to get out of sync when the appearance is cloned.
AvatarService -- add two new methods, GetAppearance and SetAppearance
to get around the lossy encoding in AvatarData. Preseve the old
functions to avoid changing the behavior for ROBUST services.
AvatarAppearance -- major refactor, moved the various encoding
methods used by AgentCircuitData, ClientAgentUpdate and
ScenePresence into one location. Changed initialization.
AvatarAttachments -- added a class specifically to handle
attachments in preparation for additional functionality
that will be needed for viewer 2.
AvatarFactory -- removed a number of unused or methods duplicated
in other locations. Moved in all appearance event handling from
ScenePresence. Required a change to IClientAPI that propogated
throughout all the IClientAPI implementations.
