With the ISO C bindings in Fortran 2003, we can get a Fortran pointer
from a C pointer. This means it is actually possible to pass "strided
memory" from NumPy to Fortran libraries in a portable way. A Fortran
pointer is more similar to a NumPy view array than a C pointer. If I am
not mistaken, fwrap can generate the boiler-plate Cython and Fortran code.
