Revert sampling parameter initialization workaround

1D image sampling used to be treated as 2D image sampling with the
second coordinate being ignored. But a bug was causing us to use the
second component of the 'offset' parameter. This was worked around by
initializing all parameters provided to the sampling routine.

This costs some performance, and since we've fixed the 'offset' bug and
have specialized handling of 1D images now, the workaround can be
reverted.
