[NTG-context] m-graph: metapost errors in demo

[Christopher Creutzig]

Salvete,

  is it just me or does

texexec --pdf -mode=demo m-graph

really not work?  I get very many metapost errors, starting with a bunch of

! Redundant equation.
<to be read again>
                    ;
l.140 Gmargin.low=-.07;



(which are rather harmless) and continuing with

 >> 0
 >> vacuous
! Not implemented: point(known numeric)of(vacuous).
<to be read again>
                    ,
<forever> ...c_:=false;r_:=Gpp_(point0of(vacuous),
 
Gxcvlin_,Gycvlin_)if.path(...

Gscan_->...:&cycle.fi.fi;exitunless.Gdidsc_;endfor

                    ;
l.335 gdraw "agepopm.d";


and similar fatal errors.


Best regards,
