Dear Toni,

I'm a bit surprised from your conclusion from the indeed good discussion 
from Monday.

> 1. Ability to free memory: currently xml3d.js never frees memory
This is wrong. We only talked about external loaded resources being 
cached for possible reuse. This is NOT related to any other memory 
managment in xml3d.js. The caching strategy for the raw data can be 
improved and I filed an issue for that:
https://github.com/xml3d/xml3d.js/issues/25

Even without this we can easily load and render scenes of large sizes.

> 2. Ability to load data in the background (parse meshes in worker): 
> currently xml3d.js loading can be synchronous only

Doing this is in the responsibility of the mesh format handler plug-in 
and is possible today (though not tested). However, we want to provide a 
better integration with the resource management.
