fped/gui_canvas.h
werner 0b241a14fe Dragging a frame into the canvas now works. It's built on top of the frame
tool, with all the old code still around, so the code paths are a bit obscure.

- gui_frame_drag.c: use GTK_DEST_DEFAULT_MOTION instead of
  GTK_DEST_DEFAULT_HIGHLIGHT
- gui_frame_drag.c: put meat on the frame and canvas drag and drop skeleton
- gui_frame_drag.c (setup_frame_drag, setup_canvas_drag): use GDK_ACTION_COPY
  instead of GDK_ACTION_PRIVATE
- gui_frame_drag.h, gui_frame_drag.c (is_dragging_anything): new helper
  function to check if we're dragging anything, without specifying what
- gui_canvas.h, gui_canvas.c: added thin interface layer between gui_frame.c 
  and gui_tool.c
- gui_canvas.c (enter_notify_event, leave_notify_event): return FALSE so that
  other widgets can get the events, too
- gui_tool.h, gui_tool.c (tool_hover): return whether we found anything to 
  hover on
- gui_tool.h, gui_tool.c: added interface for dropping a frame on the canvas
