Function get_table_xy_or_coord

src/sp_lev.c:3187–3204

Get x and y values from a table (which the caller has already checked for * the existence of), handling both a table with x= and y= specified and a * table with coord= specified. * Returns absolute rather than map-relative coordinates; the caller of this * function must decide if it wants to interpret the coordinates as * map-relative and adjust accordingly. */
