PROJ/src/projections/ob_tran.cpp, branch backport-2856-to-master

Remap ENOMEM from PROJ_ERR_INVALID_OP to PROJ_ERR_OTHER

2020-12-15T16:53:29+00:00

Revise error codes to have a reduced set exposed in the public API.

2020-12-15T00:13:43+00:00

Fixes #2482

And also add proj_context_errno_string()

Revise gie 'expect failure errno XXXX' strings

API cleanup: unexport number of internal symbols, and remove/replace a few unused ones

2020-11-30T00:35:59+00:00

Remove old pj_ memory (de)allocation functions

2020-11-20T15:40:40+00:00

Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary
function as API memory functions in proj_api.h is no longer there and
the other use as a workaround for old errno problems is no longer valid
either.

Replaced with malloc and free across the codebase.

src/projections/: remove assignments in expression and multiple statements per line

2020-03-08T18:58:35+00:00

Should hopefully result in no change in results, and hopefully more
readable code...

ob_tran.cpp: add comment to link maths with Snyder's formulas

+proj=ob_tran +o_proj=longlat: set right unit to PJ_IO_UNITS_WHATEVER so as to be able to chain with unitconvert (fixes #1525)

2019-03-20T18:58:25+00:00

Rename PJ_IO_UNITS_ANGULAR to PJ_IO_UNITS_RADIANS

2019-01-03T14:31:38+00:00

This communicates better what the unit actually is. It also opens the
door for potentially adding PJ_IO_UNITS_DEGREES in the future in order
to coordinates in degrees correctly as well.

Merge projects.h into proj_internal.h
