in LuaTeX (on the lua side) everything works with scaled points (when a <dimen> is expected).

For example, when you create a new kern node:

k = node.new("kern")
k.kern = 2 * 2^16 -- that is 2 TeX points


I confused <dimen> in the explanation in the TeXbook with <glue>. Thus I assumed glue_spec nodes in the parshape table of tex.linebreak().
