Hi Stef,

You suggested that to me some time ago and I did. Sophie uses 
smallintegers for coordinates. This is ok for books, to go from printer 
pixels to books of several kilometers. But I want float coordinates and 
multiple nonlinear coordinate systems in the same world. I don't want to 
be restricted to Cartesian with a single scale all over the system. In a 
morph, the number 3 could mean 3 milimeters, and in another it could 
mean 3 astronomic unit (mean distance from the earth to the sun), or 3 
degrees of latitude north, or 3 db or whatever.

Cheers,
Juan Vuletich
