The icon used for tables and views, is either:
- unadorned of any decoration
- decorated with a green plus
- decorated with a red minus
We have empty views (i.e. returning no rows), some are unadorned,
others are red-minus. When we select from them, from SQLiteSpy or SQLite's
both views appear "correct" (no errors are produced).
So what's the meaning of those decorations?
I can't find any doc that describes this.
