further on the background of the split (as I did it ;-)) :
actually it was mainly not because of the size but because I wanted to
use TextureObjRefChunks, still be able to control the environment and
avoid code duplication.
So a little bit I would prefer to keep it separated (but I see the
complicated part of it). We could move it back to TexObj and add
something like a FullEnv chunk which can override the TexObj settings.
Adding another chunk might be overkill.
Another option would be to add it to either TexObjRef (too) or TexBase
that looks kind of strange, but a workable solution.
Or we keep it inside both (worst case IMHO) but this might be to
confusing (even if the winning rules are clear). Especially for
tools.
