... as discussed in fltk.coredev in thread "RFC: introduce public
config header <FL/fl_config.h>", see:
https://groups.google.com/g/fltkcoredev/c/xLCs1AIXMVo/m/MHZpQggzAQAJ
- Rename abi-version.h to fl_config.h, rename input files,
update dependencies, .gitignore, CMake, configure and Makefiles.
- Include Cairo options in FL/fl_config.h
- Rename FLTK_USE_CAIRO to FLTK_HAVE_CAIROEXT for consistency.
- Include <FL/fl_config.h> in config.h and wherever necessary,
fix include order (move FL/Fl.H to the top) and more.
- Move USE_X11 to fl_config.h and rename to FLTK_USE_X11
- Do not include <config.h> in Cairo demo program which is no
longer required in Cairo programs since FLTK 1.4.0
This is a hypothetical fix, since the condition `count == 0` may not
be true although `doit` has been allocated. In practice this should
not be possible since the same loop is executed twice in lines 463++
and 471++. But anyway, here it is...
- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.
The main fixes are only to avoid static code analyzer warnings reported
in issue #5, but there are also minor bug fixes included. These bug
fixes are more of theoretical concerns though.
Close#6.
This function is replaced by static Fl_Window_Driver* Fl_Window_Driver::(const Fl_Window *win).
The purpose is to have class Fl_Window_Driver outside from FLTK ABI.

This change was previously attempted at r.12792 but the test/offscreen demo did not run well with it.
This commit fixes the problem: the global fl_window should not be changed when drawing to
an Fl_Double_Window.

At this point, Windows FLTK apps detect HighDPI displays and rescale their GUI accordingly. They also
all reply to ctrl/+/-/0/ keystrokes to enlarge/shrink/reset their windows.

This second step replaces FL/x.H with FL/platform.H in all source files.
Dependencies have been adjusted as well.
This commit completes the replacement of FL/x.H with FL/platform.H.

With this, most MacOS FLTK app can be scaled with command/+/-/0/ keystrokes.
A scaling problem remains, visible in test/cube, where the "Test" string is not positioned correctly.
GLUT apps can also be scaled (across platforms).
SVG images are re-rasterized after app scaling for optimal drawing.

A bug was visible in test/unittests when moving between lines and rectangles.

It's still necessary to compile with -DFLTK_HIDPI_SUPPORT
to activate the new HiDPI support.
Default builds get the same HiDPI support as in FLTK 1.3

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.

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.
