Metapost - text alignment

["Young, Robert" <Robert Young dsto defence gov au>]

G'Day,
 
I've just downloaded the latest Dia (previously using 0.94), and I've
noticed that the Metapost export horizontal alignment is a little
broken.
 
Looking at the code, it appears that it's due to the text line
improvements - Metapost is now told to left align all text and this
doesn't work well.
 
I'm willing to spend a little time trying to fix this.
 
Lars - should I implement a draw_text and draw_text_line method for the
Metapost export? Or what would you recommend? 
 
I can't promise to make this "perfect", but I would like the centre,
left, and right aligned text to be honoured once again.
 
Thanks,
Rob.
