Under gnome, Tweaks -> Fonts ->Scaling factor allows to change
the size of all fonts handled by gnome.
With that change, FLTK apps obey to changes to Xft.dpi.
Previously, the display scaling factor value under gnome was sought in the gnome
database using the gnome_scale_factor() function. But that information is no
longer present.
File $HOME/.config/monitors.xml was also used to get that information.
Using the Xft.dpi X resource is simpler and more general because it's
effective both for gnome and KDE.
The procedure to set screen scaling factors becomes:
1) each screen scaling factor is set to 1
2) the OS is queried according to each platform to get screen scaling factor
values
3) The value of FLTK_SCALING_FACTOR, if present, is used to multiply
scaling factors
Gnome now seems to store the value of the display scale factor in file
$HOME/.config/monitor.xml. Previously, that value was readable with
the gsettings command.
The present commit uses the information found in that file
and reverts back to the gsettings command if that information is not found.

As Manolo pointed out the questionable variable was not used (read)
in this case of the switch statement, hence it can be removed.
Thus, Fl_cocoa.mm is completely independent from code of libfltk_gl.

The problem was visible with test/cube: when the window was minimized, only the left GL subwindow
was captured in the window icon.

The new procedure essentially resizes the window, as done on the X11+EWMH and Windows platforms.
This improves in particular the possibility to turn an Fl_Gl_Window fullscreen on and off.
MacOS ≥ 10.10 is required because the procedure isn't stable (random crashes during fast switches) with 10.9.

The original intention of FL_PORTING was to mark all places in the
source code where changes are required to port FLTK to a new platform.
Thanks to the driver system, this approach has become somewhat
misleading, so I removed all references.
