[NTG-context] how to simulate \hss in luametatex?
Hi list,
I want to simulate \hss in lua end in ConTeXt/luametatex environment.
For example,
```ConTeXt
a{\raise 1.5ex\hbox to 0pt{\hss b}}c
```
should get 'b' on top of 'a', as follows:
```pdf
b
ac
```
and in lua, I see a before "b" node, width
width:0, stretch:65536, shrink:65536, stretchorder:2, shrinkorder:2
And in lua, I do as follows(part of my app seen in attachment):
```lua
local hss = node_new(glue_id)
hss.stretch = 65536
hss.stretchorder = 2
hss.shrink = 65536
hss.shrinkorder = 2
hss.width = 0
list,_ = node_insertbefore(list, list, hss) -- b is in the list
-- I got a with
width:0, stretch:65536, shrink:65536, stretchorder:2, shrinkorder:2
local box = node_new(hlist_id, "box")
box.head = list
box.width = 0
box.shift = -tex_sp("1ex")
-- I got width:0 height:0 deep:0
shift: -503424
head, current = node_insertbefore(head,current, box) -- current is 'c' node
```
And got 'b' on top of 'c' in pdf as follows:
```pdf
b
ac
```
How can I get 'b' on top of 'a' as \hss do?

Re: [NTG-context] Page break with placement of a figure at the bottom of the page
Hi,
Sorry to come back to you, but it seems to me that there is enough space
here.
