Working towards the dragging of frames. Changed the press/drag/release logic of
tables such that items are selected on release and we can thus drag without
selecting. (From a user point of view, selecting would be fine. But selecting
may sometimes cause a change_world or similar, destroying the widget, which
upsets drag and drop.)
- gui_frame_drag.c (setup_var_drag, setup_value_drag): moved targets to file
scope
- gui_frame_drag.c (has_target, drag_var_motion, drag_value_motion): Gtk
doesn't check target compatibility for us, so we have to do this explicitly
- gui_frame_drag.c (drag_begin): don't leak the pixbuf
- gui_frame_drag.c (is_dragging, drag_end), gui_frame_drag.h: for drag vs.
activations on button release, we now can test what is being dragged. For
this, we have to explicitly clear the variable "dragging" when done.
- gui_frame_drag.c (setup_var_drag, setup_value_drag): moved common setup to
setup_drag_common
- gui_frame_drag.c (setup_frame_drag, drag_frame_motion), gui_frame_drag.h,
gui_frame.c (frame_select_event, build_frame_label): added infrastructure for
dragging frames
- gui_frame_drag.c (setup_canvas_drag, drag_canvas_motion), gui_frame_drag.h,
gui_canvas.c (motion_notify_event, make_canvas): added infrastructure for
dragging to the canvas
- gui_frame.c (table_var_select_event, table_value_select_event, build_table):
split logic into press and release action, so that we can drag without
implicitly selecting

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
