[DGD] preserving vars after lib recompile

[Petter Nyström]

The below is all from my quite possibly fogged view of how DGD works.

No, it doesn't. If you want to recompile the object to use the changed
lib, what you need to do is to first destruct the lib and then
recompile the object. Recompiling the object will automatically
compile the inherited files needed. Unless there is a change of
variable declarations in the lib, no data will be lost in the
recompiled object. All data that belonged to the lib object is however
lost when you destruct it - so don't keep data in library objects.

Rather, I would destruct the lib and all libs that inherit that lib.
Then I would recompile *all* master objects that inherit any of the
destructed libs - this in order to make sure all objects around use
the updated lib. But that is not mandatory, DGD allows having multiple
objects inheriting different versions of the same lib.

I don't know. =)
