[Insight-developers] differences in itkMultiResolutionPDEDeformableRegistrationTest results due to portable-rounding and pixel-centeredness

[Michel Audette]

Hi Bill,

the recent baseline files predate Tom's latest commit. I have not committed
anything this week, including regression data. They do not seem to be
inconsistent with Tom's fix, however. The number of failing tests with flags
on is the as same as prior to the fix.

Best wishes,

Michel
