Instead use getImage and let the caller create the Texture. Sharing of textures is then handled in post by the SharedStateManager.
This is closer to what the OSG serializer does.
Streamlines the TextureManager and will make it easier to multithread.
Improves intersection testing performance, shaving off ~2ms of frame time in exteriors.
Also increases terrain loading time by ~1ms per cell, so will have to look into background loading soon.
