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.

5dbfe413ae Fix computation of Fl_Window::decorated_w() and decorated_h() when apps are resized through display setting. 
Under Windows 10:
when the user sets the value of "Change the size of text, apps and other items" in display settings
to above 100 %, the computation of Fl_Window::decorated_w() and decorated_h() has to
take the scaling factor into account.
This factor is also necessary to draw correctly window title bars.

aafd8b6031 Fix VisualC++ build (Visual Studio 2015). 
IDE generated with CMake, still many warnings, but compiles and runs.

Note: we *must* get rid of all VisualStudio-specific #define's like:

 #define unlink _unlink

This one led to a compilation error (not a warning).

src/Fl_File_Icon.cxx: I had to add _MSC_VER (WIN32) distinction as in
  previous code (FLTK 1.3). Obviously MinGW is more Unixy than MS VC++
  since MinGW compiled and linked the code. Needs a better fix ...
