Is this node the root node?
When the parent tree view is created it adds one special node, the root node. This node has no parent node and some other special features so several code paths need to check whether they are the parent node.
This also returns true for a detecthed node returned with tree_view::remove_node.

How the layout engine works.
Every widget has a member layout_size_ which holds the best size in the current layout phase. When the windows starts the layout phase it calls layout_initialize which resets this value.
Every widget has two function to get the best size. get_best_size tests whether layout_size_ is set and if so returns that value otherwise it calls calculate_best_size so the size can be updated.
During the layout phase some functions can modify layout_size_ so the next call to get_best_size returns the currently best size. This means that after the layout phase get_best_size still returns this value. Initialises the layout phase.
Clears the initial best size for the widgets.
See Layout algorithm for more information.
full_initialization | For widgets with scrollbars it hides them unless the mode is scrollbar_mode::ALWAYS_VISIBLE. For other widgets this flag is a NOP. |

Replaces all children of this tree with new children.
The motivation here is to provide a way to add multiple children without calculating the trees size for each child added. This is a waste of time since the results of that resizing will be immediately thrown out except for the final child added.
id | The id of the node definition to use for the new nodes. |
