When clipping a raster it would be nice to specify how to deal with pixels that are crossed by the clipper boundary.
The options could be:
- include pixels that are entirely within the clipper
- include pixels whose centers (and/or origins) are inside the clipper
- include pixels who intersect the clipper - not that this should not include pixels that only share an edge.
As it currently stands, minor (floating point) differences in raster extents and/or resolutions can lead to differing results
