This allows to use the virtual function mechanism to adapt scaled image drawing both to the
image type and the graphics driver type.

Possible side effect: programs that relied upon inclusion of unrelated
system headers by FL/Fl_Table.H or FL/Fl_Table_Row.H may fail to compile.
Removed include files (some only on certain platforms, list may be incomplete):
#include <FL/Fl.H> // moved to implementation (.cxx)
#include <FL/Fl_Box.H> // moved to implementation (.cxx)
#include <FL/Fl_Scrollbar.H> // moved to implementation (.cxx)
#include <sys/types.h>
#include <string.h> // memcpy
#include <malloc.h> // WINDOWS only: malloc/realloc
#include <stdlib.h> // UNIX: malloc/realloc

Fl_Text_Selection got a new method length() and returns 0 in length()
and in all offsets (start(), end(), position()) if no text is selected
(selected() == false).
The behavior in FLTK 1.3 and earlier versions (returning undefined
values if !selected()) was confusing.

Windows are now rescaled with a call to Fl_Window::resize() which has been slightly modified.
Static member variable bool Fl_Window_Driver::in_resize_after_scale_change is created,
and is true if and only if Fl_Window::resize() is called by Fl_Window_Driver::resize_after_scale_change().
This new flag allows Fl_Window::resize() to perform correctly the rescaling of the window.
Fl_Gl_Window::resize() and Fl_Double_Window::resize() also consult the value of
the Fl_Window_Driver::in_resize_after_scale_change flag.
The platform-specific Fl_WinAPI_Window_Driver::resize() and Fl_X11_Window_Driver::resize()
also use the Fl_Window_Driver::in_resize_after_scale_change flag.

Clarify that all variants of do_callback() call clear_changed() after
the callback and that 'long Fl_Widget::argument()' may truncate the
user_data value on some (particularly Windows 64-bit) platforms.
Some code has been reformatted and refactored with better variable names,
but there are no effective code changes.
Obsolete, inactive code was removed.

It is really an accessor to protected method Fl_Window::flush().
Rename it to Fl_Window_Driver::flush_Fl_Window to reflect that.

The new method Fl_Group::bounds() replaces Fl_Group::sizes() whose
internal array structure was not documented.
Fl_Group::bounds() uses the new and documented class Fl_Rect for its
internal structure.
src/Fl_Tile.cxx now uses bounds() instead of sizes().

more methods if we find we need them.

Patch proposed by Teklad (STR #3211, file #7):
http://www.fltk.org/strfiles/3211/Fl_Tabs.H.patch
with minor modifications and adjustments for FLTK 1.4.0.
Method which() is now also virtual, as suggested by guyben in comment #24.

Corresponds to STR #3320
1) HiDPI support consists in detecting the adequate scaling factor for the screen on which
FLTK maps a window, and scaling all FLTK units by this factor. FLTK tries to detect the correct
value of this factor at startup (see more details below). Environment variable
FLTK_SCALING_FACTOR can also be used to set this value.
2) Rescaling support consists in changing the scaling factor of all FLTK windows
in reply to ctrl/+/-/0/ keystrokes.
More details for the various platforms :
- X11: Support is very advanced. Some details need still to be improved.
Automatic detection of the correct starting value of the scaling factor works well
with the gnome desktop. The present code contains no support for this on
other desktops. FLTK_SCALING_FACTOR provides a workaround.
-WIN32: Support is incomplete at this point, although many test
applications have partial or complete HiDPI and scaling support.
The current value of the system's scaling factor is correctly detected
at application startup. Apps respond to changes of this value in real time.
Support needs to define the FLTK_HIDPI_SUPPORT preprocessor variable
at compile time. This way, standard builds produce a code with the
default WIN32 HiDPI support, that is, where all graphics goes to an internal
buffer that gets enlarged by the system and then mapped to the HiDPI
display. To experiment with (or develop) the new HiDPI support requires
a modified build procedure in which FLTK_HIDPI_SUPPORT is defined
at compile time. When the support will be complete, the requirement for the
definition of this preprocessor variable will be removed. The present commit
contains support for a single scaling factor. Eventually, per-screen scaling
factors should be implemented, as done for X11.
- MacOS: this commit does not give new HiDPI for this platform.
Eventually, window rescaling in reply to command/+/-/0/ is desirable.
Per-screen scaling factor makes no sense on this platform because
the OS itself takes care of the difference between the resolutions of
traditional and retina displays.

Solves STR# 3381.
Also: standardized doxygen comment style in both files;
> /** */ doxygen commenting

Removed some confusing non-doxygen comments, and rewrote some confusing ones.
Removed old license info Matt had imported from my original 2002 widget..
there was no reason for it to be in there; the Fl_Table code inside FLTK
is licensed under the FLTK GPL license, no need for the extra noise in the docs.

As proposed in STR #2750 and #2752: only status quo, i.e.:
- no new method Fl_Input_Choice::maximum_size(int) (STR #2750 and #2752)
- no handling of FL_Down key to open menu (STR #2752)

Previously Up/Down keys worked only if one of the buttons was pressed
before so that it had the focus.
test/valuators.fl: The second Fl_Spinner widget (FL_FLOAT_INPUT) now has
wrap mode disabled whereas the first one (FL_INT_INPUT) uses wrap mode
(default, compatible with FLTK 1.3.x and older).
