Add FLTK_BUILD_SCREENSHOTS option info to CMake build summary
...
+ build screenshot programs if option FLTK_BUILD_SCREENSHOTS=ON:
don't `EXCLUDE_FROM_ALL` because the option must be set anyway.

Add an option and the first program to create screenshots
...
This is the first step in creating additional programs for saving
screenshots for documentation purposes. These screenshots must be
saved in the documentation/images directory and checked into the
Git repository.
These programs allow developers to create new screenshots or change
existing ones. More screenshots may be created by programs in the
/test/ folder.
To-do: add more *new* screenshot programs, and if useful, move some
existing programs from the `/test/` folder to `/screenshots/`,
such as `test/resize-example*.cxx` and maybe more.

Fix "Wayland's wl_display_dispatch() can block a Vulkan application" ( #1354 )
...
This rewriting of the FLTK callback function that runs when there are data available
for reading in the socket connecting the app and the Wayland compositor is meant to
facilitate the integration of Vulkan.
This rewriting reproduces the recommended code to read from the socket
documented in Wayland function wl_display_prepare_read_queue() when several threads
potentially read from the socket.

... to the Doxygen generation log file `documentation/pdfall.log`.
The additions to the log file are intended to find out which parts
take how much time.
Note: use `grep "make_pdf" documentation/pdfall.log` to see the
log output with timestamps.
- documentation/Doxyfile.in: exclude undocumented source files in
src/xutf8/* which reduces parsing by a small amount of time,
estimated about 5 percent of build time. YMMV.

Since FLTK 1.5 building FLTK in the source tree is prohibited by our
CMake setup. Therefore all build artifacts are stored in the build
tree and don't need to be "ignored" in the source tree.
This simplifies the .gitignore files significantly.
There are some exceptions though, for instance .cxx and .h files
generated by fluid which might be created by a user/developer
executing fluid in the source tree.

CMake: execute `code_snapshot` separately for each file we want to
scan so we can create timestamps and generate PNG images only if
the source file (e.g. unicode.dox) was modified.
documentation/src/unicode.dox: remove output folder `generated`, use
only the filename. CMake sets the current working directory as needed.
util/code_snapshot.cxx: format and improve comments, reset code buffer
so we can generate multiple images per input file.

This method can be used to set a more appropriate color average to
prevent "graying out" the box colors of the 'plastic' scheme.
Alternatively environment variable 'FLTK_PLASTIC_AVERAGE' can be used
to set the color average value. See docs for details.
Set color average to 45% in test/unittests demo program.
