gctp wrapper does not work properly.

although frank and even does not seem to think this code is even used in the driver anywhere it is very useful code for replacing gctp in applications like swath2grid

gctp expects to receive and returns lat/lon in radians.

the old version leaked large amounts of ram in the inv transformation.

the old version was very costly to use, because the transform was created for every point transformation.

Brian,

I would suggest just committing it in trunk.

I am cc:ing Andrey who may have interest.

It looks fine to me, please go on commiting it.

Just for record: the wrapper itself is not used in the HDF4 driver, but HDF-EOS library uses it (instead of GCTP). We are not using HDF-EOS functions which depend on coordinate conversions though.

Best regards,
Andrey
