... "when there's no current window".
Silently ignore GLUT function calls that need a current window if the
current window is NULL, return 0 from functions that return an 'int'.
Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers().
This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise.
Note: the chosen implementation to ignore GLUT calls silently appears
to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error
messages and exit. The latter could be implemented as well but would
be much more work.
The user can add an arbitrary number of highly configurable
shell commands through the setting panel. The commands can
be saved as user preferences, inside the .fl file, or exported
to an external file. Shell scripts can be limited to individual
platforms, can have shortcut keys, etc. .

The previous member Fl_Wayland_Graphics_Driver::create_shm_buffer() is now
renamed to create_wld_buffer() and divided in 2 parts:
- one is related to the draw buffer;
- the other is related to the wl_buffer and is what is now called create_shm_buffer().
This allows to delay creation of the wl_buffer until absolutely necessary,
done inside Fl_Wayland_Graphics_Driver::buffer_commit().
This code was (and is still) commented out but it *would* trigger
a "stack buffer overflow" error *if* uncommented.
The new code demonstrates how a binary object (Fl_Preferences 'bed')
can be dumped to a preferences file in binary format (if activated).
Todo: fluid-shared can't (yet) be built agains the shared fltk lib
because of some linker errors. Needs investigation.
Note: fluid-shared is basically a test program to demonstrate linking
against the shared FLTK libs but doesn't work yet using VS (MSVC).
This is no problem for the functionality.
The process to generate the docs now uses the full Doxyfile as given
by `doxygen -u Doxyfile.in` with a specific doxygen version, in this
commit version 1.8.14.
There's only one addition: 'HTML_COLORSTYLE = TOGGLE' which has been
added to doxygen in version 1.9.5. We're using it now to give the user
the choice to select a "dark mode" or "light mode" theme if the docs
are generated with doxygen 1.9.5 or later.
Unknown doxygen tags are now filtered silently and logged in files
documentation/Doxyfile_error.log and documentation/Doxybook_error.log,
respectively.
Most (if not all) doxygen tags introduced after 1.5.5 are commented out
to avoid doxygen warnings about obsolete or unknown tags, except
those tags that need a specific value.
Add 'HTML_COLORSTYLE = TOGGLE' (since 1.9.5) for better user experience.
With this tag users can switch between dark and light mode *if*
the docs were generated with doxygen 1.9.5 or later.
Enable search engine.
Log doxygen conversion errors and warnings to Doxy*_error.log,
i.e. silence the doxygen conversion process.
documentation/src/index.dox: Remove background color from html
index page for better contrast when using dark mode.
