Resampling on geographic CS #2
Description
Resampling methods should take into account that a grid's spatial coordinates may be defined on a coordinate reference system (CRS), hence the grid is positioned in some, e.g. geographic WGS-84 coordinate system (CS).
Under the assumption that source and target CRSes are the same, the resampling methods need additional parameters to specify the source and target grid's positioning and pixels sizes: easting, northing, pixel_size_x, pixel_size_y.
Note that we don't need the CRS itself as a parameter under the given assumption.
