Detailed Description

Why not use MDirection? It's limited by valid astronomical coordinates on the sky Hz vs arcsec does not fly.

The idea here is to represent a point, line, plane, etc. (depending on the dimensions of the coordinate system and the coordinate contained here) and eventually have positions which can convert themselves to match different coordinate systems used in other images; removing some of the tangle of linToWorld(...) et al. that snakes through canvases and display datas currently. It may well be that some of this may need to remain in the current canvases/datas, but at least the viewer (and regions) will be able to talk about positions independent of the rest of the viewer hierarchy.
