Sounds OK to me. 

Looking at the textres.josn file I see that there is no magnitude field.  
Where will this come from for the object text?

I also note that the file uses the corner coordinates of the texture, rather 
than the size and rotation.  I guess this is more flexible - I would 
imagine we can specify non-square images.  However, it's less accessible 
for third parties to use.  I guess I'll have to get on an implement a 
nebula editor.
