to stdout if not - there's no reason anymore to disallow editing the offset in new-style measurements - struct inst_ops is no longer opaque, so we can avoid adding even more silly little access functions and open-code straightforward callbacks - (re)stuctured hover/click/drag logic in gui_tool.c - added optional debugging output to gui_canvas.c - don't let a vector's base be dragged onto the vector's own end or onto one of its children - measurements can now be properly changed by dragging git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5414 99fdad57-331a-0410-800a-d7fa5415bdb3
