[Opensim-dev] Renaming innerscene

[Michael Wright]

I'd rather have some separation of 3d/ base scene level and region level, so that it is easier to customise things change things in applications based on opensim. Not every application is going to want all the region level things, and some might not even want any. They might just want a basic multi user 3d scenegraph with their own higher level handling. 

I think there has to be a base layer than handles 3d objects in the world with support for adding/removing 3d objects, updating physics etc. And sends updates to the clients, and accepts avatar movement commands back. This is basically what InnerScene does or should do.  We can separate higher level functions above this all we want.

But without that base layer that other applications can build on top of, OpenSim loses so much flexiblity and interest.

all complicates things horrendously.
There are actions that change between Scene and InnerScene 4 times 
to get the job done. That could be done much more efficiently if 
those methods were combined and then split up into functional units, 
rather than "3d" scoped.

One flow I found was like this:

Caller calls Scene:A
Scene:A calls InnerScene:A
Scene:A calls Scene:B
Scene:A calls InnerScene:C
InnerScene:C calls Scene:C
Scene:A returns.

This is overcomplex and baffling to new coders. I am not surprised 
that many people choose not to touch it.

Needless to say, I removed the above flow and made it into a single 
call into InnerScene. It was part of attachment rezzing. When i did 
that, I streamlined that flow.

I believe InnerScene and Scene should not be separate, or not be 
separated along the line they are separated now.

On the name, I don't really care.

+-0 there.
