Scalable2i class
Scalable x, y coordinates at the zoom level.
zoom must be a positive integer.
Coordinates x, y and zoom have integer values.
Scalable coordinates are coordinates associated with some level of detail
(LOD) or zoom level. They are used for example by tiling schemes to
represent pixels and tiles of tile matrices.
