Thought again, to solve the filtering issue, too.

I just thought... What if I use a "base" model and a "derived" one that
stores the extra columns plus a "pointer" to the row in the "base"
model?
For lists (GTK_TREE_MODEL_ITERS_PERSIST set), the pointer could be a
GtkTreeIter. The problem is keeping it in sync with model changes... Too
bad that it seems GtkTreeRowReference doesn't use any optimization on
models with persistent iters :-( Or am I wrong ?
