This example greatly simplifies the test/editor example to focus on
just the mechanics of dynamic style buffer manipulation via the
add_modify_callback().

Replace "MSWindows" with "Windows".
To do: README.Windows.txt (and maybe other documentation as well)
needs updates.

opengl apps were left out of the targets list on purpose
so that only non-opengl apps would build.
TODO: Determine a way to detect the presence of fltk opengl libs
from within the Makefile using only fltk-config, so as to
conditionally build the opengl examples.
Do NOT use fltk's own build system (../makeinclude or cmake)
to determine this, so the Makefiles will work as user examples.

Since svn r12443 we can use all labeltypes (including FL_IMAGE_LABEL and
FL_MULTI_LABEL) w/o leading underscore. We can also use both documented

These warnings and errors were found using gcc 6.1 (64-bit) under Windows.
The error in examples/howto-add_fd-and-popen.cxx (-fpermissive) is due
to the wrong definition of Fl_FD_Handler under Windows 64-bit (FL_SOCKET!).
This should really be fixed in a better way in FLTK 1.4.

Everything related to Fl_Tree and its test and demo programs has been
cleaned.
Documentation needs updates.

Methods Fl::event_x_pixel() and Fl::event_y_pixel() committed at r.10941
are removed. Instead method Fl_Gl_Window::pixels_per_unit() is added.
The documentation explains in more detail how to write cross-platform
FLTK code supporting high resolution OpenGL windows on retina displays.
The examples/OpenGL3test.cxx app exercises Fl_Gl_Window::pixels_per_unit().

Use show(argc,argv) to enable command line arguments and colors,
fix indentation, Windows compilation warnings, and change tab
selection color, which was too dark on my Win7 system (low

colors easier, if needed.

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:

Also: added some related demo code to tree-simple to demonstrate
'reselect' callbacks, where a callback can be invoked when an item
that's selected already is 're-selected'.

o Changed behavior of example to be more predictable
o Enter key can be used to toggle edit mode
o User can navigate table cells with arrow keys or tab/shift-tab without slipping into cell edit mode

o Replaced hard coded row/col counts.
o Enabled arrow keyboard navigation (setting Fl::OPTION_ARROW_FOCUS)
o Fixed small bug in handle() that was calling Fl_Table::handle() instead of Fl_Table_Row::handle()
that was preventing Fl_Table_Row's row selection from working..

This example was written before 1.3, and was dependent on the 'old' FLTK behavior
where arrow keys could be used to navigate widget focus (in addition to Tab).
The 'new' FLTK behavior (1.3 and up) disables arrow key focus nav by default,
which is bad for this program, so we enable the old FLTK behavior with Fl::option().

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..
