PROJ/test/unit, branch 6.0.0

Transformation: reintroduce the term of 'Null geographic offset' for transformations between geographic CRS of same datum (typically 3D to 2D)

2019-02-21T12:48:28+00:00

typo fixes: s/Explictly/Explicitly/ and s/instanciat/instantiat/

2019-02-20T19:42:26+00:00

CoordinateOperation: add a hasBallparkTransformation() method that can be used to know if it includes a very approximative transformation term

2019-02-20T19:32:17+00:00

CompoundCRS to Geog3DCRS: in synthetised transformation, document in the name we are lacking an ellipsoid height to vertCRS height correction

2019-02-20T15:13:24+00:00

PROJStringFormatting: change order of emission of push/pop w.r.t axis swap/unitconvert to avoid useless simplification rules

2019-02-20T14:29:38+00:00

PROJStringFormatter: remove useless push/pop in another case

2019-02-20T12:18:20+00:00

Vertical CRS transformation: synthetize a vertical unit change transformation when needed, and also sort Null geographic offset transformation in last

2019-02-20T11:57:01+00:00

compoundCRS to compoundCRS: avoid emitting dummy 'Null geographic offset from X to X' in transformation name

2019-02-20T10:12:38+00:00

Add VERTCON grid name alternatives in database, and handle filename substitution for VERTCON method

2019-02-20T09:36:14+00:00

Fix a few issues with i386 builds

2019-02-18T21:50:16+00:00

Relax tolerances in a few unit test, and in laea code.
Seen with gcc 5.3 and also 7.1
Related to the use of the 387 floating-point math, since they
disappear with gcc 7.1 if using non-default -mfpmath=sse -msse
