Since macOS 11, configure --enable-x11 (and the equivalent with CMake)
fails when compiling fl_write_png.cxx in parsing of time.h.
The error happens only if png.h is included without time.h having
been included before.
The fix is to #include time.h before png.h
A better fix than his hack is desirable.
The bug would appear with test/device and when scaling up to 133% or above:
the background of the Porsche pixmap would be truncated.
The bug requires to set OPTION_XRENDERER=0 to appear.
README.Unix.txt and README.Windows.txt (MinGW, MSYS) instructed to
execute `NOCONFIGURE=1 ./autogen.sh` which is no longer necessary
(a simple `autoconf` does the job).
Remove files misc/config.guess and misc/config.sub because they are
no longer needed: these files are now in th FLTK root directory
available. Remove all references to these files.
Fix .gitattributes accordingly. Also exclude the .github folder
from exports, for instance when creating distribution tarballs.
src/print_button.cxx: "Print front window" implementation (new file)
This is compiled and activated if USE_PRINT_BUTTON is defined.
The feature can be fine controlled by environment variable
'FLTK_PRINT_BUTTON' (see docs in source file).
The error was reported for "centos 6 with devtoolset-6 installed
which contains gcc (GCC) 6.3.1 20170216 (Red Hat 6.3.1-3)".
The fix includes the missing header files *and* makes sure that the
correct conversions (to size_t) take place as in
src/drivers/PostScript/Fl_PostScript_image.cxx.
The new function fl_write_png() was moved to its own file and is now
publicly available ("exported") so other programs can use it.
This function was used in fluid to write a window screenshot (.png)
together with a template (.fl) to preferences storage.
Adding only 2 of 3 new examples is intentional (9 per menu level).
Figure numbers have been removed in all the HTML docs recently for
better maintainability.
add example(s) showing Albrecht's innovative overlap resizable

This undocumented macro is used on X11 and macOS platforms to
consolidate mouse move events, i.e. to collect some events and send
them later as one event. The old macro name CONSOLIDATE_MOTION has been
renamed to FLTK_CONSOLIDATE_MOTION since it is now a "global" symbol.
Users can define FLTK_CONSOLIDATE_MOTION in their build system, e.g.
on the compiler commandline, as 0 or 1 to disable or enable this
feature, respectively.
In FLTK 1.3 the default was 0 (OFF) on macOS and 1 (ON) on X11.
In FLTK 1.4 the default is always 0 (OFF).
