/******************************************************************************
* Project: PROJ.4
* Purpose: Revised, experimental API for PROJ.4, intended as the foundation
* for added geodetic functionality.
*
* The original proj API (defined previously in projects.h) has grown
* organically over the years, but it has also grown somewhat messy.
*
* The same has happened with the newer high level API (defined in
* proj_api.h): To support various historical objectives, proj_api.h
* contains a rather complex combination of conditional defines and
* typedefs. Probably for good (historical) reasons, which are not
* always evident from today's perspective.
*
* This is an evolving attempt at creating a re-rationalized API
* with primary design goals focused on sanitizing the namespaces.
* Hence, all symbols exposed are being moved to the proj_ namespace,
* while all data types are being moved to the PJ_ namespace.
*
* Please note that this API is *orthogonal* to the previous APIs:
* Apart from some inclusion guards, projects.h and proj_api.h are not
* touched - if you do not include proj.h, the projects and proj_api
* APIs should work as they always have.
*
* A few implementation details:
*
* Apart from the namespacing efforts, I'm trying to eliminate three
* proj_api elements, which I have found especially confusing.
*
* FIRST and foremost, I try to avoid typedef'ing away pointer
* semantics. I agree that it can be occasionally useful, but I
* prefer having the pointer nature of function arguments being
* explicitly visible.
*
* Hence, projCtx has been replaced by PJ_CONTEXT *.
* and projPJ has been replaced by PJ *
*
* SECOND, I try to eliminate cases of information hiding implemented
* by redefining data types to void pointers.
*
* I prefer using a combination of forward declarations and typedefs.
* Hence:
* typedef void *projCtx;
* Has been replaced by:
* struct projCtx_t;
* typedef struct projCtx_t PJ_CONTEXT;
* This makes it possible for the calling program to know that the
* PJ_CONTEXT data type exists, and handle pointers to that data type
* without having any idea about its internals.
*
* (obviously, in this example, struct projCtx_t should also be
* renamed struct pj_ctx some day, but for backwards compatibility
* it remains as-is for now).
*
* THIRD, I try to eliminate implicit type punning. Hence this API
* introduces the PJ_COORD union data type, for generic 4D coordinate
* handling.
*
* PJ_COORD makes it possible to make explicit the previously used
* "implicit type punning", where a XY is turned into a LP by
* re#defining both as UV, behind the back of the user.
*
* The PJ_COORD union is used for storing 1D, 2D, 3D and 4D
*coordinates.
*
* The bare essentials API presented here follows the PROJ.4
* convention of sailing the coordinate to be reprojected, up on
* the stack ("call by value"), and symmetrically returning the
* result on the stack. Although the PJ_COORD object is twice as large
* as the traditional XY and LP objects, timing results have shown the
* overhead to be very reasonable.
*
* Contexts and thread safety
* --------------------------
*
* After a year of experiments (and previous experience from the
* trlib transformation library) it has become clear that the
* context subsystem is unavoidable in a multi-threaded world.
* Hence, instead of hiding it away, we move it into the limelight,
* highly recommending (but not formally requiring) the bracketing
* of any code block calling PROJ.4 functions with calls to
* proj_context_create(...)/proj_context_destroy()
*
* Legacy single threaded code need not do anything, but *may*
* implement a bit of future compatibility by using the backward
* compatible call proj_context_create(0), which will not create
* a new context, but simply provide a pointer to the default one.
*
* See proj_4D_api_test.c for examples of how to use the API.
*
* Author: Thomas Knudsen, <thokn@sdfe.dk>
* Benefitting from a large number of comments and suggestions
* by (primarily) Kristian Evers and Even Rouault.
