When disabled (false), the line height adjusts dynamically to accommodate
the tallest character in each line of text.

Declares a navigation component which participates in navigation using dpad buttons of a gamepad.
It's an abstract entity which can be focused. It has it's own size and position on screen accroding to
UI cursor and passed arguments, but it won't be drawn on the screen.
Note that all navigation components which are located outside of UiWindow borders won't participate
in the navigation and will be considered as inactive

Sets a flag to ingore the navgation in a current UI scope or not. By default, if argument isn't
specified, the function sets the flag to true. If ignore is set to true, all components after the function call
won't participate in navigation as if they didn't exist on a scene. Flag resets back to false
after leaving the UI scope in which the function was called.

UiNavGroupBegin
id = UiNavGroupBegin([id])
Arguments
id (string, optional) – Name of navigation group. If not presented, will be generated automatically.
Return value
id (string) – Generated ID of the group which can be used to get an info about the group state
Begins a scope of a new navigation group. Navigation group is an entity which aggregates
all navigation components which was declared in it's scope. The group becomes a parent entity
for all aggregated components including inner group declarations. During the navigation update process
the game engine first checks the focused componet for proximity to components in the same group,
and then if none neighbour was found the engine starts to search for the closest group and the
closest component inside that group.
Navigation group has the same properties as navigation component, that is id, width and height.
Group size depends on its children common bounding box or it can be set explicitly.
Group is considered in focus if any of its child is in focus.
