Re: [matplotlib-devel] A new KNOWNFAIL, pcolormesh.png ?

[Michael Droettboom]

I'm not sure PIL enters into it -- there shouldn't be any code path 
involving PIL in that case.

I think this a case where the image comparison tolerance needs to be 
increased.  You would do this be passing a "tol" parameter to the 
image_comparison decorator on the pcolormesh test.  The default is 1e-3, 
but it should be conservatively increased until the test passes.  You 
can perform this experiment yourself, or attach the result image for the 
test to this list and I can experiment to find a correct value.
