…uction managed by OgreWorld.

… can start. Next I need to figure out the instancing shaders etc. All of this is still very much WIP.

… more logic to the instance state objects in OgreWorld, including optimization runs after 5 seconds after creations/deletions have been done.

…instead of the deprecated GetEntity(). Check that all these places have proper null checking in preparation for instancing.

…ne() and GetAttachementEntity().

…ouse to reset any active camera.

…perty/slots. Add function that can set mesh refs instances as static, this can boost performance quite a bit but is hard to automatically detect (if static any movement wont be updated) so lets leave it to script logic to tell the rendering what instance meshes wont be touched. Improve destroying instances so that the manager gets cleared once it has 0 instances left.

…eparated from the supershader for now.

…s to test performance with both instancing on and off and toggling static instancing.

…sh targets with ref and submesh. Fix that meshes that are set as static also create new instances (with all of its submesh/material combos) as static. Added a getter for static instancing for a particular mesh ref.

…eWorld.

…ill usually override both or none so this makes the output cleaner to read. Fix documentation that CreateInstance can return null in error situations with given input.

…fied from the Ogre 3D example assets and note the original author Matias N. Goldberg.

… empty targets into the internal lists. Now if create and destroy are used in pair correctly, there is nothing left for dtor to cleanup. Fixed typo in script UI.

…ncing is used. Add todo tag to SetMaterial. Implementing this might be quite heavy with instancing as it involved completely destroying the current instances with this material and creating new with 'instancing supported highlight material'.

…state book keeping. This fixes meshes with multiple submeshes in them and makes the internals a faster when instances are destroyed by EC_Mesh.

…needed test code for multi submesh creation.
