[EMBOSS] Graphics glitch emboss 3.6.1

[David Mathog]

Finally built 3.6.1 for 32 bits on a 64 bit machine and verified that it
runs there and on 32 bit machines (all linux).  There is however an odd
graphics glitch wherever it runs.  For instance:

pepwheel -sequence=test -sbegin=1 -send=353 -graph=X11

results in a graph that is similar to that on another system (6.0.1
on Solaris) but has:

1:  thicker lines
2.  diamonds that don't close.  They look like this (ascii art, used
a fixed space font)
     ^
    / \
   /   \
  +    /
      /
   __v

That is, if the start is at the "+" and has coords (x1,y1) and the
point v has coords (xv,yv), then it looks like the line that is supposed
to go back to (x1,y1), goes instead to (x1,yv).
