* Add special check for non-rotated global grids We usually read global grids from file and they get rotated depending on the wesn selection. However, when a global grid is passed from another environment, as GMT_IS_REFERENCE, we may be projeting that image in gmt_grd_project and if the repeated meridians fall inside the map (since no rotation has happened) they are counted twice, yielding a slightly different result. Only applies to gridline-registrered grids. This fix detects this special situation and skips one of the repeated meridians. * Handle meridian to be duplicated * Update gmt_map.c * Update gmt_project.h
