[metapost] gdraw and negative numbers

[Jørgen Larsen]

With MetaPost 0.901 the gdraw command (from the graph package) seems to 
have a problem with negative numbers in axis labels: the minus sign is 
placed far too low.
(I have tried the MP that comes with teTeX 3.0 and the MP that comes 
with XemTeX, and they both give the same (wrong) result.)


Here is a very minimal example:


prologues:=2;
input graph;
beginfig(1)
  draw begingraph(2cm,2cm);
    gdraw (-1,-1);
   endgraph;
endfig
end.

and the resulting eps-file is
