[matplotlib-devel] figure size changes when calling pylab.show

Hi,

i have found a strange behaviour of the figure size. At least for some 
cases it looks like the figure size is changed by a small amount after 
calling pylab.show.

The attached script saves the same figure before and after calling 
savefig. The figure saved after the call to show is a different in 
number of pixels.


Here comes a printout from running the script in ipython:

In [1]: %run figsize_truncation.py
desired figsize: (3.1496062992125986, 3.1496062992125986)
actual figsize: [ 3.1496063  3.1496063]
desired figsize: (3.1496062992125986, 3.1496062992125986)
actual figsize: [ 3.2875  3.2875]

As you can see on the last line the last figure becomes something else.
