They +would return coordinates in the full room. This would make sense when +drawing points for example, or when evaluating functions on the boundary. + +Implementation of this is an issue that requires some thought. Adding an extra +"Embedded" type for each grid would make it easy to understand each type but +contribute to "type bloat". On the other hand adapting existing types to +handle embeddedness would complicate the now very simple grid types. Are there +other ways of doing the implentation?
