Added to assist cand for his patch to solve RFE STR #2828 option (I).
o Add move() methods to Fl_Tree_Item.
o Add deparent()/reparent() methods
o Supporting methods added to Fl_Tree_Item_Array, and enhancement
to update_prev_next() to allow -1 option to create an orphan item
Added to Fl_Tree_Item:
* Fl_Tree_Item* deparent(int pos)
* int reparent(Fl_Tree_Item *newchild, int pos)
* int move(int to, int from)
* int move(Fl_Tree_Item *item, int op, int pos)
* int move_above(Fl_Tree_Item *item)
* int move_below(Fl_Tree_Item *item)
* int move_into(Fl_Tree_Item *item, int pos)
Added to Fl_Tree_Item_Array:
* int move(int to, int from)
* int deparent(int pos)
* int reparent(Fl_Tree_Item *item, Fl_Tree_Item* newparent, int pos)

a volatile method that can be overridden by
subclasses to take drawing control of tree item's content.
This replaces the old "item_draw_callback()" technique
added a few months ago as an ABI feature; turned out the
new technique is a better way to go.
o The examples/tree-custom-draw-items.cxx demo adjusted
accordingly.
o Added missing docs for some methods that had none,
including label_[xywh]().
o Added related methods needed to implement this, including:
Fl_Tree_Item_Array::replace()
Fl_Tree_Item::replace()
Fl_Tree::root(item)
Fl_Tree::add() variations
Fl_Tree_Item::drawbgcolor()/drawfgcolor()
o Carefully worked the FLTK_ABI_VERSION macros so as to be
ABI compatible with 1.3.0.
o Verified 1.3.0 ABI compatibility with ABI Compliance Checker 1.99.8.5:

git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10071 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
These are problems "ABI Compliance Checker" found with the recent
Fl_Tree mods.

***************************************************************
NOTE: You MUST uncomment the FLTK_ABI_VERSION in Enumerations.H
to use these changes.
***************************************************************
Also: separated tree size calculation from draw() code,
so that one can cause the tree to recalculate immediately
after making modifications to the tree by calling Fl_Tree::calc_tree().
Numerous improvements to docs for the tree as well, enough
to create a rather large diff.
Large internal changes were needed to do this properly.
The following was added to the CHANGES file:
- Fl_Tree: various related changes:
o Added horizontal scrollbar
o Separated draw() and tree size calculation
o Added new public methods:
> resize() -- uses optimized dim calc, avoids tree recalc
> next_item() -- added parameters: direction, visibility
> extend_selection() -- added parameters, improved algorithm
> calc_dimensions() -- calc tix/y/w/h, tox/y/w/h and scrollbars
> calc_tree() -- calc tree_w/tree_h
> recalc_tree() -- schedules calc_tree()
> first_visible_item(), last_visible_item(), next_visible_item()
> first_selected_item(), last_selected_item(), next_selected_item()
o Added protected variables:
> _tix/y/w/h -- tree widget 'inner' dimension
> _tox/y/w/h -- tree widget 'outer' dimension
> _tree_w,_tree_h -- entire tree hierarchy width/height
o Deprecated:
> item_clicked() -- use callback_item() instead
> first_visible() -- use first_visible_item() instead
> last_visible() -- use last_visible_item() instead
- Fl_Tree_Item: various related changes:
o Added Fl_Tree ptr: needed for auto-recalc when item modified directly
o Added new methods tree(), recalc_tree()
o Added new ctor that accepts Fl_Tree*
o draw() parameters changed to include tree size calculations
o Deprecated:
> ctor using Fl_Tree_Prefs parameter (Fl_Tree* version better,
and must be used for 1.3.3 ABI features to work correctly)
> next_displayed() -- use next_visible() instead
> prev_displayed() -- use prev_visible() instead
- test/tree: added tests for newly added features

o Added examples/tree-custom-draw-items.cxx to demonstrate its use.
o Fixed small doc error for recent Fl_Tree::get_selected_items()

with this as the default color, Fl_Tree::color() can control the tree's background.
Tests added to the test/tree application.
o test/tree.fl modified:
o Added a 'Test Suggestions' button to document various tests
o Added tests for new 'transparent' color behavior
o Added test for STR#2832 to check if items can be drawn to the /right/ of child widgets
o Added new methods to Fl_Tree_Prefs:
item_labelfont() -- obsoletes labelfont()
item_labelsize() -- obsoletes labelsize()
item_labelfgcolor() -- obsoletes labelfgcolor()
item_labelbgcolor() -- obsoletes labelbgcolor()
o Added 'Fonts and Colors' section to Fl_Tree docs
o Fl_Tree_Item ABI feature added: using bitflags instead of chars
to keep the class small, as it gets instanced a lot. (fast + LIGHT)
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9478 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
to allow widgets to control the size of items in the tree
(instead of vice versa).
o Added item_draw_mode(int) to allow for easier bitflag maintenance,
since enums don't seem to be typesafe yet.
o Tree demo modified to demonstrate this feature.
An important feature for adding large widgets to tree items.
Will probably add an example, 'tree-of-tables' to demo this usage.
o Small doc fixes.
o Had to rename FL_TREE_ITEM_DRAW_WIDGET_ONLY to FL_TREE_ITEM_DRAW_DEFAULT.
Its meaning for the bit fields changed when new bit fields were added.
(The prev name just didn't make sense in the new context. Since it was
just a few svn commits old and an unreleased ABI feature, it shouldn't
affect anyone not in R&D)
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9404 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
o new calc_item_height() -> const
o Added a needed ABI ifdef
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9380 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
o Fix STR#2828 (E): {Vertical|Widget} Gap
o Moved Fabien's reselected methods to Fl_Tree_Prefs,
return method made const, doxygen, removed underbars from methods
(to follow general API)
o Widgets can now appear to the right of labels.
This can be controlled with item_draw_mode(FL_TREE_ITEM_DRAW_LABEL_AND_WIDGET)
o Cleaned up Fl_Tree_Item::draw(), Fl_Tree::draw()
o New methods:
marginbottom() -- [ABI feature] extra space below last tree element when scrolling
widgetmarginleft() -- [ABI feature] space to left of widget
usericonmarginleft() -- space to left of usericon
labelmarginleft() -- space to left of label
item_draw_mode() -- control how items, widget() are drawn
o Updated Fl_Tree docs, tree-elements.png
o test/tree: added sliders to test the above new features,
added "open all" and "close all" buttons
o Probably other stuff..
TODO: Fix "scroll-beyond-bottom" (STR#2796)
TODO: Fix other items in STR#2828
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9377 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
Added _next_sibling and _prev_sibling to Fl_Tree_Item class to make
next_sibling() and prev_sibling() more efficient during item selection.
Used new FLTK_ABI_VERSION macro (as designed by Greg and Albrecht on fltk.dev) to protect the ABI breaking features.

Fl_Tree::labelsize() -> item_labelsize() -- TO AVOID COLLISION WITH Fl_Widget::labelsize()!
Fl_Tree::labelfont() -> item_labelfont() -- TO AVOID COLLISION WITH Fl_Widget::labelfont()!
Fl_Tree_Prefs (internal) changes:
Fl_Tree_Prefs::fgcolor() -> labelfgcolor() -- for consistency with above
Fl_Tree_Prefs::bgcolor() -> labelbgcolor() -- for consistency with above
Fl_Tree_Prefs::selectcolor() removed -- uses Fl_Widget::selection_color() instead
Fl_Tree_Prefs::inactivecolor() removed -- was unused; inactive color procedurally calculated
Other Fl_Tree mods:
o Fixed bug with select_all(item) and deselect_all(item)
(they were not limiting themselves to children of specified item)
o Fixed bug with item not drawing in its /own/ bgcolor when item selected
o Fl_Tree uses the Fl_Widget::selection_color()
o All methods that deal with 'font types' changed int -> Fl_Font
o All methods that deal with 'font sizes' changed int -> Fl_Fontsize
o Added needed methods to Fl_Tree for accessing colors:
item_labelfgcolor() -- access default fg color used for new items
item_labelbgcolor() -- access default bg color used for new items
tree_connectorcolor() -- access the connector line color
o Small doxygen comment adjustments and general clarifications
o test/tree demo modified to include testing of new label color methods, cleanup

* 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)

o Added user_data() to Fl_Tree_Item
o Added insert() and add() methods that allow specification of Fl_Tree_Prefs
o Changed Fl_Pixmap args to Fl_Image for more flexibility
o Fixes for positioning of items in the presence of user icons
o find_children() changed from protected -> public
