458d063643 Image classes: memorise the width and the height of the cached form of the image to support GUI scaling

916b44e361 New member function Fl_Image::scale(int width, int height) to set the FLTK size of an image.
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.

8e558595e6 Make virtual member function Fl_Image::draw_scaled(int X, int Y, int W, int H) protected rather than private.
Consequently, remove the trailing _ from its name reserved for private class members.

eae09e7fa0 Create virtual Fl_Image::draw_scaled_(int X, int Y, int W, int H) and its implementations for image classes.
This allows to use the virtual function mechanism to adapt scaled image drawing both to the
image type and the graphics driver type.

f48750b0f4 Introduce HiDPI + rescaling support for the X11 platform (+ partial support for WIN32)
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.

41e22f2f39 Move ifdef's in RGB_Image into driver system.

- cleaning up (Xlib and GDI will likely throw syntax errors. Trying to fix ASAP)

5a71578b1b Doxygen pdf documentation: Changed pdf mime type to application/pdf. Removed all Widget class headers from file section as they already are in the class section, this saves many pages. Also disabled the referenced by/from systematic inserts for each functions as this is more a core developer documentation feature than a fltk user manual feature, also saves many pages. Didn't use the LATEX_COMPACT feature yet, not happy with its result, will comment it later.

f5a1576d7c added doxygen comments for undocumented methods of Fl_Bitmap and Fl_Browser
also replaced some html with doxygen equivalent.

note that not all comments are consistent. some are one-liners, even though
the contain [obvious?] parameters, and others have \param and \returns.
note too, that some parameter names are ambiguous and require type info,
eg line could be FL_BLINE* for whole line entry, or int for line number,
and this can make descriptions awkward (\param line line number).

classes: new copy(), copy(w,h), desaturate(), color_average(), and
inactive() methods, alloc_xyz member for copied data, etc.

Updated test programs to use inactive() and copy() methods to create
inactive images for the test buttons, plus the inactive button to toggle
it...

Added start of separate image classes, a la 2.0, for various image formats.
FLUID will also be updated for it...
