[NTG-context] Strange problem with metapost graphics
Hi all,
Here is minimal example of some trouble I have:
...
\startMPinclusions
numeric u; u=1cm;
\stopMPinclusions
\starttext
\startuseMPgraphic{dummy}
drawarrow (0,0)..(8u,0);
label.bot(\sometxt{temps}, (7u,-.5u));
\stopuseMPgraphic
\placefigure[fig:Uncontratdanslaflèchedutemps]{Un contrat dans la flèche du
temps}{\useMPgraphic{dummy}}
\startuseMPgraphic{ummy}
pair A[];
A[0]:=(-1u, -1u);
A[1]:=( 6u, -1u);
A[2]:=( 6u, 4u);
A[3]:=(-1u, 4u);
draw A[0]--A[1]--A[2]--A[3]--cycle withpen pencircle scaled 1pt;
label.bot(\sometxt{Dupont}, A[0]);
label.top(\sometxt{Smith}, A[2]);
\stopuseMPgraphic
\placefigure[fig:Boîte d'Edgeworth]{Boîte d'Edgeworth}{\useMPgraphic{ummy}}
\stoptext
.
The trouble is that this compiles nicely with pdftex, a little less nicely
with xetex, and badly with luatex, tested at home and on context live.
- xetex: the label in the first graphic appears with bad size.
- luatex: first label in the second graphic appears with bad size and font,
and second label disappears; but if I comment out the label in the first
graphic, the second graphic is as expected.
Any idea?

A much smaller luatex test is possible:
\startuseMPgraphic{a}
label.bot(textext(a), origin);
\stopuseMPgraphic
\useMPgraphic{a}
\startuseMPgraphic{b}
label.bot(textext(b), origin);
\stopuseMPgraphic
\useMPgraphic{b}
There is some problem with the textext array indices, it seems:
report error: (0,0,_tt_w_2,0,0,1)
! Transform components aren't all known.

at the end of mp-mlib.mp add
def resettextexts =
_tt_n_ := 0 ;
enddef ;
extra_endfig := extra_endfigresettextexts ; ;
then run
ctxtools --touch
context --make (or texexec --make --luatex)

Done! But same result :-(
