Hi,

I've been working on a possible new coordinate framework on a side branch.
This is still missing a lot of functions, but the general direction should
be visible already.

Ideas:
 - Coordinates have units, so they are not scalar and cannot be used as
   scalars
 - All coordinates are in nanometers internally, so -DEESCHEMA and co can
   go away afterwards
 - The compiler should check whether we are using the correct units, at no
   runtime cost
 - Transition should be done with a compatibility layer that generates
   warnings.

There is still a lot missing here, like UI lengths (pixels), zoom factors
(pixels/nm) and angles/rotation. Most of what is needed will turn up only
when I start actually replacing "wxPoint" with "point".

Questions? Comments?

   Simon
