fped/meas.h
werner 9c68c0de34 - File>Save now saves to a file if a second name is given on the command line,
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
