  With this change, it works !

  Now, back to the "resize" function.
  Basically it works : I was confused with the previous problem.
  But the "autoselect" button does not work as expected.

  If I place a drawind in the middle of the bed, any size selected, only
  the bottom line is at the right place, the other ones are at the
  top/left/right ends of the format.

  Why is the color set to 25 instead of 55 in xsane-preview.c, line 5505 ?
  (this has no effect for my problem)
