inst->base and inst->u.meas.end are swapped, causing fped to crash in vec_at. Also introduced a universal swap() function. - util.h (swap): new swap function for arguments of any type - gui_meas.c (begin_drag_move_meas, draw_move_meas): swap the endpoints if moving an inverted measurement - coord.c (sort_coord): use swap() instead of swap_coord - coord.h, coord.c (swap_coord): removed - gui_util.c (save_pix_buf): use swap() instead of open-coding the swap - kicad.c (kicad_centric): use sort_coord instead of "manually" sorting the coordinates git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5968 99fdad57-331a-0410-800a-d7fa5415bdb3
