===============================================================================
Various test material, mostly converted from selftest entries in PJ_xxx.c
Contrary to the material in builtins.gie, this material is handwritten and
intends to exercise corner cases.

Two ob_tran tests from nad/testvarious

Two tests from PJ_molodensky.c

Same thing once more, but this time unabridged

-------------------------------------------------------------------------------
Some tests from PJ_pipeline.c
-------------------------------------------------------------------------------
Forward-reverse geo->utm->geo
-------------------------------------------------------------------------------
operation proj=pipeline zone=32 step
proj=utm ellps=GRS80 step
proj=utm ellps=GRS80 inv
-------------------------------------------------------------------------------

expect 12 55 0 0
Now the inverse direction (still same result: the pipeline is symmetrical)

-------------------------------------------------------------------------------
And now the back-to-back situation utm->geo->utm

-------------------------------------------------------------------------------
Test a corner case: A rather pointless one-step pipeline geo->utm
-------------------------------------------------------------------------------
operation proj=pipeline step proj=utm zone=32 ellps=GRS80
-------------------------------------------------------------------------------

Finally test a pipeline with more than one init step
-------------------------------------------------------------------------------
operation proj=pipeline step

init=epsg:25833 step
init=epsg:25833 inv step

-------------------------------------------------------------------------------
Some tests from PJ_vgridshift.c
-------------------------------------------------------------------------------
operation proj=vgridshift grids=egm96_15.gtx ellps=GRS80
-------------------------------------------------------------------------------
Appears there is a difference between the egm96_15.gtx distributed by OSGeo4W,
and the one from http://download.osgeo.org/proj/vdatum/egm96_15/egm96_15.gtx
N(12.5, 55.5) = -36.021305084228515625 (download.osgeo.org)
N(12.5, 55.5) = -35.880001068115234000 (OSGeo4W)
This is annoying, but must be handled elsewhere. We jump through the hoop by
setting a very lax tolerance.
-------------------------------------------------------------------------------

A number of tests from PJ_helmert.c
-------------------------------------------------------------------------------

This example is a coordinate from the geodetic observatory in Onsala,
Sweden transformed from ITRF2000 @ 2017.0 to ITRF93 @ 2017.0.
The test coordinate was transformed using GNSStrans, using transformation
parameters published by ITRF: ftp://itrf.ensg.ign.fr/pub/itrf/ITRF.TP

-------------------------------------------------------------------------------
This example is from "A mathematical relationship between NAD27 and NAD83 (91)
State Plane coordinates in Southeastern Wisconsin":
http://www.sewrpc.org/SEWRPCFiles/Publications/TechRep/tr-034-Mathematical-Relationship-Between-NAD27-and-NAD83-91-State-Plane-Coordinates-Southeastern-Wisconsin.pdf
The test data is taken from p. 29. Here we are using point 203 and converting it
from NAD27 (ft) -> NAD83 (m). The paper reports a difference of 0.0014 m from
measured to computed coordinates, hence the test tolerance is set accordingly.
-------------------------------------------------------------------------------

rotation matrix is updated when necessary.
