Summary: rater.py: division by Zero

Initial Comment:
I would like to report a bug (or rather strange feature
:) ) in
pyx/graph/axis/rater.py. If I specify limits of axis
equal to [12.5 to 1050] then pyx crashes somewhere in
rater.py:

------
Example program:

from pyx import *

g = graph.graphxy(height=8, width=8,
                  x=graph.axis.linear(min=12.5,
max=1050, title=r"\large{X}"),
                  y=graph.axis.linear(title=r"\large{Y}") )

g.plot( graph.data.list( [[0, 50], [10, 50]],
addlinenumbers=0, x=0, y=1),
   
graph.style.line(lineattrs=[style.linewidth.thick,style.linecap.round])
)

g.writetofile("test.eps")

-------
Output:

Traceback (most recent call last):
  File "test.py", line 10, in ?
    g.writetofile("test.eps")
  File

    self.finish()

    axis.finish(self.axespos[key])

line 313, in finish
    newrate = self.rater.rateticks(self, newticks,
self.density)
  File "/home/markov/python/pyx/graph/axis/rater.py",
line 193, in
rateticks
    return rate/weight
ZeroDivisionError: integer division or modulo by zero

cheers,

Marko
