yes, that's why I liked it so much that I posted the quick hack.
The next step might be to use it in Java2DConverter and routines like
Way.clockwise().
It might also be used to beautify roundabouts and other zig-zagging
caused by rounding errors.

no, it uses two spare bytes (a Coord instance allocates 16 bytes (8 byte alignment)
with the patch 12 bytes are used, still leaving 4 spare bytes)
