2021-12-20Fix and additional options for Peirce Quincuncial projections (#2978)Toby C. Wilkinson
This fixes the current forward implementation of Peirce Quincuncial proj to correctly flip/reflect out the southern hemisphere to four triangles, and rotate entire result to a square or diamond. (It there resolves the issues identified with pull request https://github.com/OSGeo/PROJ/pull/2230 , where southern hemisphere was wrongly projected over northern, and reverses the restriction to northern hemisphere introduced there). It also adds additional lateral projection of the hemispheres. - This PR adds an optional parameter `+type` which allows selection of projection. The `+type=square` and `+type=diamond` types match in principle ESRI's twin implementations of square and diamond PQ projs. The **default** if not specified is `+type=diamond`. - The previous behaviour restricted to the northern hemisphere can be reproduced using the `+type=nhemisphere`, though this is an edge case only. - An additional `+type=horizontal` and `+type=vertical` rectangular lateral versions have been added that place each hemisphere side-by-side. This is primarily to allow creation of projections such as Greiger Triptychial, which also require the additional optional params `scrollx` or `scrolly` in order to shift parts of the projection from one side of the map to the other. - Additional documentation has been added to proj description, including quoting the usual meridian used in common usage of projection, and images showing the different types.

2021-10-23CMake: revise how we deal with symbol export and static buildsEven Rouault
- Remove the explicit PROJ_MSVC_DLL_IMPORT symbol used for importing symbols from a MSVC .dll: by default on MSVC, we use now __declspec(dllimport), unless PROJ_MSVC_DLL_EXPORT is defined by PROJ at build time. This makes it easier for users: they don't have to define anything special. This simplifies in particular the build of our binaries - For static builds, export -DPROJ_DLL= as public, so that users that import PROJ through CMake mechanism don't have to do it manually.

2021-10-21Add fallback_strategy to tinshift transformJohannes Schauer Marin Rodrigues
- this bumps format_version of tinshift JSON to 1.1 for the new field fallback_strategy - the default behaviour without that field is retained - if fallback_strategy is set to "nearest_side", then points that do not fall into any of the triangles will be transformed according to the nearest triangle - if fallback_centroid is set to "nearest_side", then points that do not fall into any of the triangles will be transformed according to the triangle with the nearest centroid

proj_factors(): accept P to be a projected CRS (fixes #2854)
2021-09-30proj_factors(): accept P to be a projected CRS (fixes #2854)Even Rouault
Updated doc: Starting with PROJ 8.2, the P object can be a projected CRS, for example instantiated from a EPSG CRS code. The factors computed will be those of the map projection implied by the transformation from the base geographic CRS of the projected CRS to the projected CRS. The input geodetic coordinate lp should be such that lp.lam is the longitude in radian, and lp.phi the latitude in radian (thus independently of the definition of the base CRS, if P is a projected CRS).
