Graphics drivers now use up to 6 virtual member functions to support Fl_Image
drawing in the context of GUI and image rescaling :
virtual void draw_pixmap(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_bitmap(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_rgb(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy)
and
virtual void draw_fixed(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_fixed(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_fixed(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy)

Each image has now two sizes implemented as follows:
- the pixel size is stored in private members pixel_w_ and pixel_h_
with public accessors pixel_w() and pixel_h()
- the FLTK size is stored in private members w_ and h_ and read by w() and h()
- when the image is constructed, the two sizes have the same value
- the protected w(int) and h(int) member functions set both FLTK and pixel sizes.
- the public scale(int, int) member function is essentially nothing but
set the FLTK size and don't change the pixel size.
- when the image is drawn, its FLTK size determines how big it is drawn, its pixel
size determines how much data are available to draw it.
FLTK 1.3.4 with FL_ABI_VERSION=10304 contained an equivalent member function
but only for the Fl_Shared_Image class.

These were introduced at r12647, that is, during development of the 1.4 API.
These functions provided windowless support only on the MacOS platform,
where this can be obtained without those functions.
Windowless support on other platforms would require changing the event
loop. There's no evidence from STR's there's a demand for windowless mode
on other platforms.

This commit also simplifies the platform-dependent support of fl_read_image():
only Fl_XXX_Screen_Driver::read_win_rectangle() contains platform-specific
code to capture pixels from the current window or from an offscreen buffer.
Platform-independent function Fl_Screen_Driver::traverse_to_gl_subwindows()
captures subwindows that intersect with the area fl_read_image() targets.

The default handling of cmd-Q/Quit program under MacOS was to terminate the
program if all its windows are closed without returning from FLTK's event loop.
This was running against a strong design feature of FLTK that programs
should always complete their event loop and return from main() when cleanly
terminating.
In the new code for the MacOS platform, cmd-Q/Quit program no longer terminates
the program. Instead, the event loop is interrupted and a call to Fl::program_should_quit()
allows to detect that program termination has been requested, if necessary.

The following is valid, documented, "standard markdown" for headers in doxygen:
This is a level 1 header
========================
This is a level 2 header
------------------------
Upgrading doxygen from 1.7.4 to 1.8.13 fixed the problem.
So beware of 1.7.4 wrt to these kinds of header markdown;
the result in the docs was no header, the header text + underbars
were appearing inline with the text, crlfs removed.
Not sure exactly what version of doxygen this was fixed in;
a search in their bugzilla for 'headers' seemed to show no
directly relevant matches, other than maybe bug #681898.

Some labeltypes and boxtypes were missing a #define for the enum
without a leading underscore and the corresponding setup function
to initialize the internal table of boxtypes and labeltypes, for
instance _FL_MULTI_LABEL. This is now fixed so (hopefully) all boxtypes
and labeltypes can and _should_ be used w/o leading underscore.
Note: if there are still boxtypes or labeltypes that can't be used w/o
leading underscore this should be considered a bug and is to be fixed ASAP.

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.

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.
