x= / y= labels default format is wrong

Hello all,

I routinely work with images sizes > [1000,1000].
There is a slight annoying problem whatever the backend I use:
Pixels coordinates default format is wrong.
It does not make sense to display "x=1.42e+03,y=1.92e+03".
Pixels coordinates should be formated *by default* as integers.

Would it be possible to fix that?

Steps to reproduce:
import numpy
import pylab
a=numpy.random.random((2000,2000))
pylab.imshow(a,interpolation='Nearest')
