[Insight-developers] fixing a few remaining failing tests relating to pixel-centered coordinates

[Luis Ibanez]

Hi Michel,

You may actually find useful to write the test that Bill suggests.
It may help solve some of the remaining failing tests.

It all depends on how close you feel you are to solve the remaining
issues.


   Thanks,


     Luis
