2018-04-16Prefer proj_math.h over math.h when geodesic.c is compiled as part of PROJKristian Evers
2018-04-16Collect custom C99 math functions in proj_math.hKristian Evers
We are relying more and more on C99 math functions. On C89 systems where those functions are not available our own custom versions of those functions are used instead. So far these has been spread across the code base. This commit gathers them in the same file and introduces the proj_math.h header. The build system checks for C99 math functions. If not found the proj_math.h header make sure that C99 functions are defined as their pj_ equivalent. Ideally proj_math.h is included instead of math.h. This removes the need for any checks against HAVE_C99_MATH in the code making it easier to read. For this commit the functions hypot, log1p and asinh has been taken care of.

2018-04-14Dont do false easting/northing on cartesian coordsKristian Evers
False easting and northing should only be applied to projected coordinates (PJ_IO_UNITS_PROJECTED). This commit removes the option of false easting/northing on operations suchs as helmert and deformation that both work on cartesian coordinates.

2018-04-13Fix segfault in deformationKristian Evers
When transforming coordinates outside the grid model the deformation operation failed spectatularly. This is now fixed by checking that the coordinate is inside the grid. If it isn't an error is returned and a debugging log message is issued. Closes #934

2018-04-13Always ignore out-commented lines in cctKristian Evers
Previous to this commit cct would return the following $ cct -c 2,3,4 -t 0 -I +proj=cart +ellps=GRS80 BLAH 3579685.56545 508396.50343 5236837.50646 8.0832413787 55.5578176654 99.9833 0.0000 8.0832413787 55.5578176654 99.9833 0.0000 where the second input should not be parsed as a valid coordinate. With this commit that no longer happens and the input is returned verbatim back to the user. Closes #932

2018-04-12Enhance the precision of Spherical Mercator projection near the equatorJavier Goizueta
This uses a linear approximation of tan(x+pi/4) for better precision at small latitudes. As a result points of latitude 0 maintain a 0 Y coordinate and 0,0 is transformed to 0,0

The file seem to be unused by the packagers and we don't use ourselves. Instead of trying to keep it up to date with each release we might as well get rid of the thing.
