@oesteban This should be a fairly quick review. This fix is necessary for a release, regardless of whether we get in other improvements. |

Replaces #300, correct? |

The
_collocation_matrixfunction introduced in #301 could produce slightly different knot spacings if the field of view changes sufficiently in resampling. The results of this function should be based entirely on the size of the input image, not a dynamic resampling.We therefore calculate the grid spacings before any resampling. This eliminates the need for a separate
_collocation_matrix, which can be done with a single call toscipy.sparse.vstack()over an iterable of sparse matrices.Closes #307.
