Parameters such as towgs84, nadgrids and geoidgrids was previously only
handled by pj_transform(). This commit add a compatibility layer in
proj_create() by calling the pj_cs2cs_emulation_setup() function. This
function sets up a handful of predefined transformation objects on the
PJ object that is being created. Each of these transformation objects
are related to the cs2cs-style parameters we are trying to emulate in
the 4D API. That is, if the +towgs84 parameters is used we create
P->helmert with the parameters specified in +towgs84. Similarly for
+axis, +nadgrids and +geoidgrids. When these transformation objects
exists we use them in the prepare and finalize functions in pj_fwd/
pj_inv. If no cs2cs-style parametes are specified we skip those
parts of the prepare and finalizing steps.

With the introduction of the "inverted" flag on PJ objects
you can no longer rely on checking that the inv, inv3d and inv4d
functions are available on said PJ object. The function is used
internally a few places and otherwise exposed in proj_api.h to
ensure that users of the old programming interface can safely
check if an operation has an inverse.

arbitrary dimensionality in test code
* Call trans func of same dimensionality as input in gie
* Refactor prep/fin code for pj_fwd/pj_inv 2D,3D,4D
* Remove prime meridian handling from pj_transform (now handled in pj_fwd_prepare/pj_inv_finalize)
* Introduce prep/fin skips, mostly in support of axisswap and pipeline drivers
* Refactor fwd/inv subsystem
* pj_transform: Let pj_fwd/inv handle scaling
* Let pj_fwd/inv3d fall back to 2D eventually

Having non-const variables of static lifetime or even global scope is
usually a bad idea. These variables are inherently constants, and this
should be enforced.
This required marking some functions as not modifying input parameters
and marking some pointers as pointers to const.
One advantage is that the compiler usually puts const static variables
in a read-only code segment, so they can't be modified physically.
This can be verified with `nm` (on POSIX systems).
To avoid changes to the public API, functions returning non-const
pointers to data tables were left intact, but the returned data may not
be modified. Internally we prefer using the proj_list_* functions over
the pj_get_*_ref functions, because the former return const pointers.

* Free format now in cmd lines, in gie, and in init files
* Corrected handling of defaults
* Add demo of integrated definition and validation
* Repair stack-smashing memmove in get_init
* repair paralist corruption, clean up debug output
* Install test files for nmake builds
* Add many improvements following suggestions by @schwehr
* Be consistent in requiring lower case everywhere in gie.c
Also, this Fixes #703 and Fixes #697

Increase the focus on PJ_COORD as primary datatype: Eliminate use of PJ_TRIPLET etc.
Trim proj.h by removing material that has become unnecessary.
Improve constness
Make proj_factors work in proj.h space, by providing a trimmed down PJ_FACTORS (which even has more meaningful field names)

* Replace pj_ell_set with reimplementation supporting ellipsoid inheritance
* remove unreachable code from pj_ell_set.c
* Swap steps, so ellps args are read first, in accordance with historical behaviour
* Add ellipsoid tests to CI targets
* Reduce some optimistic tolerances
OS/X appears to have a slightly off float handling, resulting in differences at the nanometer level. Switching to 10 nm.
|
|
* Introduce geodetic-geocentric conversions, as PJ_xxx style conversion step and as API entry points
* minor improvements and minor bug squashing
|
|
* Support numerical factors only
* Make sure h positive. Improve some comments
* Let pole overshoot check have effect even for geocentric latitudes
* Factor-typological constants, now all returning false, for backwards compatibility
|
|
* Poder dual autochecking implementation
* Debugging aid: Improvements in PJ_vgridshift.c and gie.c
* Most likely, the bugbeing tripped is in the gridshift code, so. uncomment suspicious lines in deformation.gie and merge this to support the debugging effort
|
|
proj_create is now indifferent whether or not proj definition terms start with a '+' character. Also, improve gie to support testing this.
|
|
|
|
* enter proj_angular_input and proj_angular_output, exit proj_angular_left and proj_angular_right
* remove unused variable 'unit'
* In gie: remove unused func 'torad_if_needed', and add static keyword where needed
* In gie: add some comments

PJ_OBS eliminated, API adjusted to reflect that we now have only one 4D data type.
2 new API functions added to determine output types of a PJ.
|
|
* Remove a number of debugging calls and memory management from the inner loop of the pipeline drivers
* An attempt at handling inverted steps in a more straightforward way
|
|
* Linguistics: Clarify this and that, here and there
* Revert nullification of PJ_cart->fwd, inv
|
|
* Remove PJ_OBS from the API surface, rename pj_obs_api.c to pj_4D_api.c
* Repair proj.def
