The standard layout node. Expects the layout properties, which must be
compatible with the layout description D provided, which also determines
the type that contains the children. A unique ID must be provided, and a
renderable is optional - it will be passed to staging if provided. The
layer, if provided will create a new layer operation with the given color
and rotation. This is normally used to do correct transparency.
Represents an arbitrary layout node that hasn’t been staged yet. The vast
majority of the time, components should simply use the standard Node
implementation of this trait, which handles most common layout cases.
However, some components, like the text component, have complex layout logic
or special cases that Node can’t cover.
