BUG: use fitpack's regrid if possible, fixes #286
Also fixes parts of #1364 (strange warnings not transpose).
Also fixes parts of #1072 (strange behaviour, not lack of
BUG: fix and test ticket #776 and first part of #703
The new regrid backend fixes these cases
BUG: test for ticket #898 which was fixed with rebase backend
Note that non rectangular grids may still have this bug
Looks good to me.
The only thing is that this doesn't actually fix the bugs in the strict sense, but it hides them (calling the same thing with .ravel()ed grid should still cause the old issues). I'll add some comments to the tests to indicate this.
There is also some backward compatibility concern, but I don't think this is an issue since the results will only be more robust than before.
Thanks, merged in 152de29
Please take a look at the small additional changes I made.
