  Notes:


                       Jeroen's Theory of Docking

  Because if I don't write this down, no one will *ever* figure this out!

  We assume here we're docking a horizontally oriented bar inside a horizontally
  oriented dock.  Vertical orientation works, of course, completely analoguous.

  Docking a floating bar.  When dragging a floating bar, we call findDockNear()
  to determine which dock site this bar could dock into.  This dock site is a
  sibling of the current widget remembered in the drydock variable.  The routine
  findDockNear() invokes insideDock() to determine if a docking could take place
  or not.

  Not all dock sites are available for docking.  Some dock bars have a preferred
  orientation and can not be docked everywhere.  To this end, the dock bar
  maintains a member variable allowed which contains the set of sides that the
  bar is allowed to dock at.

  When findDockNear() returns a non-NULL value, a potential dock site has been
  found; a timer is set to dock at this site if the cursor hovers near its
  current position:- we don't dock immediately, since the user may be just moving
  the bar across a potential dock site on his way to another place on the screen.

  When the dragging ends, or when the timer expires, the bar is docked at the
  dock site.  Subsequent dragging will simply move the bar inside the dock site,
  and just rearrange the dock site.

  Floating a docked bar.  When moving a docked bar, dragging it simply rearranges
  the order of the bars inside the dock, until such time that the bar is substantially
  moved away from the dock site, as determined by insideDock().  Then the dock bar
  is reparented under the toolbar shell and subsequent movement will simply move
  the floaring bar.

  The function insideDock() determines if a proposed position is to be considered
  docked or non-docked.  This is determined differently, based on whether the bar
  is currently docked or not:

    1 If the bar is docked, we consider the proposed bar position undocked when
      the upper edge is FUDGE pixels above the dock site, or when the lower edge
      is FUDGE pixels below the dock site.

    2 Alternatively, if the bar is floating, we consider the bar position docked when
      the upper or lower edge of the bar is within PROXIMITY inside the dock site.

    3 In addition to 1 and 2, we also require that the horizontal alignment of the
      dock bar and dock site are within a certain TOLERANCE. This is determined
      differently depending on whether the bar is wider than the site or not:

        a If the bar is wider, we want the dock site within -TOLERANCE to
          bar width + TOLERANCE relative to the bar.

        b If the dock site is wider, we want the bar to be within -TOLERANCE to
          docksite width + TOLERANCE relative to the site.

        c A minor wrinkle is that if the bar is stretched (LAYOUT_FILL_X), we
          don't use the current width of the bar in the above calculations,
          but the default width instead; this is because a subsequent undocking,
          which would shrink-wrap around the dock bar, leaves a smaller widget
          and this may then immediately redock again.

    4 If the above tests indicate that the bar is docked, insideDock() returns
      true.

   When undocking a bar, the arrangement inside the dock site needs to stay the same
   for the remaining bars [if any].  Thus, we call undockToolBar() to inform the dock
   site that one of its bars will be removed.  Depending on its own internal layout
   algorithm, the dock site will then be able to adjust the options of the remaining
   bars so that they stay in place.

   When docking a bar, we need to figure out where the new bar goes.  To that end,
   dockToolBar() informs the dock site to determine where the new bar goes and adjust
   the layout options of the other dock bars accordingly.

   If the dock bar is moved, the dock site is informed by moveToolBar() which lets
   the dock site then rearrange the layouts according to the new bar position.
