2019-11-18createOperations(): fix so that GDA94 -> WGS 84 (G1762) still include a ↵Even Rouault
result through ITRF2008. Was broken in master by the addition of the 'WGS84 -> WGS 84 (Gxxx)' null operations in the PROJ authority
2019-11-18proj_trans(): tune selection of operation when there are several ↵Even Rouault
alternatives, to select the operation with best accuracy
2019-11-18createOperations(): small perf improvement. Do not attempt going through an ↵Even Rouault
intermediate CRS if we found direct transformation(s) but had to eliminate them due to other criteria
2019-11-18createOperations(): geocentric to geocentric operation synthetization: ↵Even Rouault
distinguish null transform from ballpark transform
2019-11-17createOperations(): remove the concept of geodetic_datum_preferred_hubEven Rouault
This was introduced in 63857c92b271bbcd10df0a032304982011acb2a9. Due to the fix done in the previous commit, we can mostly revert the above commit. We just keep the added tests and the custom WGS 84<-->WGS 84 (Gxxxx) null transformations.
2019-11-17findsOpsInRegistryWithIntermediate(): tune it to be able to research ↵Even Rouault
operations that belong to different authorities. Should make the concept of geodetic_datum_preferred_hub introduced some time ago obsolete

2019-11-12Fix proj_assign_context()/pj_set_ctx() with pipelines and alternative coord ↵Even Rouault
operations Fixes https://github.com/OSGeo/gdal/issues/1989 pj_set_ctx() only changes the context to the main object. It should also recurse down to the steps of the pipeline and the alternative coordinate operations hold in alternativeCoordinateOperations In the GDAL use case with multithreaded reprojection, and objects being transferred between thread, this would cause a failed coordinate transformation to affect an unrelated transformation of another thread...
2019-11-09Doc: document oddity related to identification of CRS from ESRI WKTEven Rouault
Or more generally formulations that don't have an explicit axis order. Refs https://github.com/pyproj4/pyproj/issues/475 projinfo 'GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]' returns EPSG:4326 with 100% confidence. But its axis order is not the same as EPSG:4326. I've pondered about this, like decreasing the confidence of the match, but this would have downstream effects on GDAL (shapefiles with the above content in a .prj would no longer be identified as EPSG:4326). So for now, document that oddity.

2019-10-30createFromWkt(): be tolerant to missing scale_factor parameter (fixes #1700)Even Rouault
This is invalid WKT, but GDAL 2.4 used to accept it and make a reasonable use of it... Currently we default it to 0 which is non sensical. Better use 1 as GDAL 2.4 did, and emit a warning. Other fix: proj_create_from_wkt() was documented to operate by default in non-strict validation mode, but it was actually in strict mode. So do as documented.

2019-10-24Generalize generalize_proj_crs_create_bound_vertical_crs_to_WGS84()Even Rouault
In recent commits, we added a generalize_proj_crs_create_bound_vertical_crs_to_WGS84() function, but there are situations where more accurate results can be obtained, if instead of specifying WGS84 as the hub CRS, the user can specify the exact hub CRS. For example the GEOID2018 grid is against NAD83(2011). So replace this function with proj_crs_create_bound_vertical_crs()
