Andrey,

Done.  I have not documented the C API bindings in the RFC, but this would be
the way to do it.  But I should stress that at this time I am not adding any
sort of broad support for the Z axis to be remapped.

Done.  I'm slightly concerned this may make handling via SWIG messier which
is why I used the simple type "int" initially.
