"Text node computes complete text layout, even if clipped to a much smaller size"
clipped could mean via a clip node, or it could mean scrolled off the visible portion of the window.
We can detect the former, but the PGNode has - ie NGText in this case - has no idea how
much work can be skipped. We could use a device clip so that when we have a Graphics
instance we know what rendering work can be skipped.
