... 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
Make clear that outside labels of widgets are not considered when
calculating the bounding box of the children (scroll area) and
include a hint to add an invisible box if necessary.
Under the X11 platform, class Fl_Native_File_Chooser will behave as follows :
- if the KDE desktop is used and if command "kdialog" is available in the path,
the Qt/KDE file chooser is used;
- otherwise, if the GTK library is available at run-time,
the GTK file chooser is used;
- otherwise, the FLTK file chooser is used.
In addition, when Fl::OPTION_FNFC_USES_GTK is off, the FLTK file chooser
is always used.
"Tiny window problem if child group larger than window"
See Greg's comment 4: "something is wrong here: either the logic or
the docs are incorrect, not sure which."
It turned out that both were incorrect.
Since we fixed the code this commit completes the STR by fixing the
docs as well so they match the behavior.
The previous name existed already with different case (fl_string.h)
in the FL folder which broke the build on macOS and Windows.
This may be a temporary fix - until I find a better way.
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.
Declare Fl_Scroll::bbox() and Fl_Scroll::recalc_scrollbars() 'const'.
These methods don't change the Fl_Scroll widget.
Use Fl_Scroll::recalc_scrollbars() in Fl_Scroll::bbox() to simplify
the code and to avoid code duplication.
bbox() can now be called at any time and returns the correct values,
no matter if draw() has been called before.
I compiled with `-Wextra-semi -Werror=extra-semi` on Linux and Windows
(cross-compiled on Linux) and removed all "extra semicolon" warnings
I could find. I didn't check on macOS (yet).
Note: Linux configured with and w/o Pango but not w/o Xft. Compilation
with other options (e.g. Cairo) might still emit such warnings.
Apple clang version 12.0.5 (clang-1205.0.22.9)
Target: arm64-apple-darwin20.4.0
Warning appeared after upgrade to Xcode 12.5 in several files,
example:
In file included from Fl_Scroll.cxx:19:
../FL/Fl_Scroll.H:102:17: warning: anonymous non-C-compatible type given name for linkage purposes by typedef declaration; add a tag name here [-Wnon-c-typedef-for-linkage]
typedef struct {

ScrollInfo
../FL/Fl_Scroll.H:104:5: note: type is not C-compatible due to this member declaration
typedef struct { int x,y,w,h; } Fl_Region_XYWH;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../FL/Fl_Scroll.H:128:5: note: type is given name 'ScrollInfo' for linkage purposes by this typedef declaration
} ScrollInfo;

Most coordinate calculations are done with the new inline function
int Fl_Scalable_Graphics_Driver::floor(int coord)
that is used by both the Windows and X11 platforms.
