For "historic" reasons,
      draw externalfigure "cow" scaled 5cm ;
normalizes the figure to a square. This will not be changed as it
is a very old feature of MetaFun.
The solution is
      draw rawtextext("\externalfigure[cow]") xsized 5cm ;
where one can use xsized, ysized or xysized (taking a pair).
That works indeed. Thanks.
draw figure "...." ...

in a future context (read luatex 1.09+) we go one-pass-mp so we can have 
a different approach (i never wanted to add a ton of code for images) so 
there externalfigure will scale proportionally too
