* Allow arbitrarily complex polygons in geod_polygon_*. In the case
of self-intersecting polygons the area is accumulated
"algebraically", e.g., the areas of the 2 loops in a figure-8
polygon will partially cancel.
* Simplify code by using C99 functions remainder and remquo.
* More test coverage.
Fixes to associated files:
* src/pipeline.cpp invoke geod_init with f = es / (1 + sqrt(1 - es))
instead of (the less accurate) f = 1 - sqrt(1 - es)
* src/apps/geod_set.cpp remove "#undef f" (a dangling relic?).

Introduced by "Merge projects.h into proj_internal.h" 8ab6f683.
|
|
This commit introduces the concept of a pipeline coordinate stack in
which components of coordinates can be saved and loaded from. This
makes it possible to moved values from one step of a pipeline to
another, effectively overwriting parts of the output from a given step.

|
make proj_create() do more or less what proj_create_from_user_input() did before (fixes #1214)
|
|
With this commit we make sure that proj_angular_input() and
proj_angular_output return the correct result for any given pipeline.
