- Declare where a new type is placed and how to create it.
-
- Placement can be as the first or last child of the anchor, or right after the
- anchor. In most cases, the anchor is the last selected type node.
-
- If the source is FROM_USER, widgets may be created with default titles and
- labels. Type created FROM_FILE will start with no label, so the label is set
- correctly later.
-
- \see Fl_Type *Fl_..._Type::make(Strategy strategy) calls `add()`

-/**
- \brief This is the base class for all elements in the project tree.
-
- All widgets and other types in the project are derived from Fl_Types. They
- are organized in a doubly linked list. Every Type also has depth information
- to create a pseudo tree structure. To make walking up the tree faster, Type
- also holds a pointer to the `parent` Type.
-
- Types can be identified using the builtin ID system that works like RTTI. The
- method `id()` returns the exact type, and the method `is_a(ID)` returns true
- if this is the exact type or derived from the type, and a dynamic cast will
- work reliably.
-
- \todo it would be nice if we can handle multiple independent trees. To do that
- we must remove static members like `first` and `last`.
-
- \todo add virtual methods to handle events, draw widgets, and draw overlays.
- It may also make sense to have a virtual method that returns a boolean if
- a specific type can be added as a child.
-
- \todo it may make sense to have a readable iterator class instead of relying
- on pointer manipulation. Or use std in future releases.
