Rasters just provides implicit casts from raster to box2d.

The idea was that casting to a bounding box isn't necessarely
the same of casting to a geometry, from a semantic point of view.

This is especially true for TopoGeometry, where you probably want
a full-defined Geometry, not a box, when casting.

But then again, maybe it is just bad to rely implicit casting...
