1) Hitting ENTER to select an item should make sure the item is
displayed if off-screen (Mayank Malik, pointing out similar behavior in Fl_Browser_)
2) show_item() without a positional argument will invoke show_item_top()
if the item is off-screen.
3) Added new method displayed() (to match Fl_Browser_'s)

* open() / close() now can invoke the callback().
New method callback_reason() lets one determine the cause.
(Used FLU's tree for reference on this)
* new Fl_Tree methods:
> item_pathname()
> show_item(), show_top(), show_middle(), show_bottom().
> next_selected_item() -- loop through the selected items.
> callback_item() -- the item that caused the callback
> callback_reason() -- reason the callback was invoked
FL_TREE_REASON_SELECTED -- item was selected
FL_TREE_REASON_DESELECTED -- item was de-selected
FL_TREE_REASON_OPENED -- item was opened
FL_TREE_REASON_CLOSED -- item was closed
> position()
> display()
* new Fl_Tree_Item methods:
> find_child_item() -- searches children for a path
> find_item() -- searches self and children for a path
> next(item) -- loop forward through tree
> prev(item) -- loop backward through tree
> first_selected_item()
> next_selected_item()
> x(), y(), w(), h()
* deprecated:
> item_clicked(). Use callback_item() instead
* the 'docallback' optional integer argument for all methods
is now back to 0 or 1 only. (Other values became unnecessary
when above new callback() behavior was defined)
* test/tree has new "Test Callback Flags" button to test the
'docallback' flags for eg. open/close/select/deselect
to make sure no bugs creep in.
* INTERNAL: added free_path() to free special path array created by parse_path().
* Various docs strengthened:
* How to use first()/next() and last()/prev() to walk tree
> made sure more method's options use \param[in]
> Added more \see references
* Moved several implementations from .H -> .cxx
* Added autoscroll to keyboard nav and mouse drags
* test/unittests: added Fl_Tree to scrollsize test
TODO:
o Horiz scroll bar (see Johannes Schock's email re. additions he sent)
o Need to allow keyboard nav to move focus to child FLTK widgets
o Fix fast-selections so that no gaps are left behind.
(Select all items from the last selected item to the current)
o Investigate non-default values of when() causing odd behavior.
(See the tree demo's when() pulldown..)
* tree demo modified to include top/mid/bot buttons that test the above.
* Keyboard navigation added:
Up/Down -- move focus
Left/Right -- closes/opens tree item in focus
Spacebar -- toggle selection state of item in focus
Enter -- selects the item in focus, deselecting all others
Tab/Shift-Tab -- change widget focus
* All Fl_Tree select() and deselect() methods now return a value
that indicates if the item's state was changed.
* Fixed focus box drawing (focus box resides more precisely within item's box)

In the future, tree.cxx and tree.h should be removed from svn
once tree.fl is merged into to the build system, so that it
generates the .cxx/.h files as part of an fltk build.
