Function layout_text 

pub fn layout_text(child: impl IntoUiNode) -> UiNode

An UI node that layouts the parent ResolvedText defined by the text context vars.

This node setups the LaidoutText for all inner nodes, the Text! widget includes this node in the NestGroup::CHILD_LAYOUT + 100 nest group, so all properties in NestGroup::CHILD_LAYOUT can affect the layout normally and custom properties can be created to be inside this group and have access to the TEXT::laidout method.
