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

2017-10-29Refactor grid shift functions.Kristian Evers
This refactoring of the grid shift functions allows for easier access to the actual grid values, as well as making it possible to perform horizontal grid shift on a single coordinate without using the pj_apply_gridshift* functions. The latter simplifies the execution path of the forward and inverse functions in PJ_hgridshift.c. This commit introduces proj_*grid_init, proj_*grid_value and proj_hgrid_apply. The init functions initialises horizontal and vertical grids respectivelive (wrappers for pj_gridlist_from_nadgrids with simpler parameters). The proj_*grid_value functions returns the specific grid value at coordinate lp. The proj_hgrid_apply function applies the grid offset to the input coordinate and outputs the adjusted coordinate.
