LayeredText class
A text node's paragraph, painted once per layer.
With no layers this is exactly the Text.rich it always was — the stack
is opt-in, and the ordinary case pays nothing for it. The state exists
only to keep the shaders a shader pass draws with across frames; without
a stack it holds nothing.
