"Arrows" in widgets are those GUI elements mostly represented by
triangles pointing in a particular direction as in scrollbars,
choice widgets, some menus, valuators and Fl_Counter widgets.
The code has been simplified and standardized such that all these
GUI elements are drawn identically per FLTK scheme.
Widget authors no longer need to write code to calculate arrow sizes
and draw polygons etc.
Different schemes can and do implement different drawing functions.
Todo: see comments "FIXME_ARROW" in src/Fl_Menu_Button.cxx and
src/Fl_Menu.cxx

Added Fltk (LGPL) license.
This widget is similar to Fl_Pack and supports either one row or one
column of widgets but has some more features. Test and demo programs
are included:
test/flex_login.cxx: simple "login window" demo program
test/flex_demo.cxx: slightly more complex demo program
The original demo programs can still be compiled and built with
the new widget provided you '#include <FL/Fl_Flex.H>'.
Backwards compatible methods are included (except debug()).
The original widget has been modified to match FLTK standards and
enhanced in several ways, including:
- support box frames
- add HORIZONTAL and VERTICAL enum values (as in Fl_Pack)
- add horizontal() method (as in Fl_Pack)
- use type() rather than internal 'direction' variable
- add standard widget constructor (x, y, w, h, label)
- add margin and gap accessors rather than hard coding constants
- improve test and demo programs
- add documentation
- replace <vector> with array as required by FLTK CMP
- rename camelCase method names, keeping old names for compatibility:
- change 'setSize(Fl_Widget*, int)' to 'set_size(Fl_Widget*, int)'
- change 'bool isSetSize(Fl_Widget*)' to 'int set_size(Fl_Widget*)'
- remove debug() method
- add a way to "unset" fixed size: set_size(Fl_Widget *, 0)
- add layout() method to force recalculation of children
- unify resizeRow() and resizeCol() methods to avoid code duplication
- improve widget size calculation.
... 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
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.
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 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.
The fluid version and other values in .fl files are written as float
values which means that locale settings apply since we enabled the
locale with "setlocale()".
Update the "rebuild" target in fluid and src folders to update
the fluid (.fl) files and related {.cxx|.h} files.
- raise minimum CMake version from 2.6.3 to 3.2.3 (Jun 01, 2015)
- indent all CMake files according to the CMP (2 col.)
- refactor FLTK version number definitions and usage
- unify CMake and autoconf/configure variable names:
- FL_VERSION -> FLTK_VERSION
- FL_MAJOR_VERSION -> FLTK_VERSION_MAJOR
- etc. for _MINOR_ and _PATCH_, respectively
- note: this does not affect FL_VERSION etc. in source code
- generate "export headers" for all libraries (experimental: OFF)
- port some forgotten goodies from branch-1.3 to master
- merge and improve macro 'create_example' (WIP)
- remove "temporary" options and code for older CMake versions
- include and use 'GenerateExportHeader' (experimental, WIP: OFF)
- note: created header files are not yet used
- build only *one* DLL with Visual Studio (tested, works)
- similar to the bundled IDE projects in 1.3.x
- add some dynamically linked test/demo programs ('*-shared')
if shared libraries are built (WIP)
- split 'macros.cmake': use one file per macro
- 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.
Test programs device and pixmap_browser use these new classes.
Class Fl_SVG_File_Surface can be optionally made non functional using the
--disable-svg configure option or turning off OPTION_USE_SVG in CMake.
Class Fl_EPS_File_Surface can be optionally made non functional using the
--disable-print configure option or turning off OPTION_PRINT_SUPPORT in CMake.
This new class is explicitly internal and undocumented. We can
rename and/or redefine or extend it as we need.
This work is based on Matt's recent update with separate internal
classes BMPReader and GIFReader which have been replaced by
Fl_Image_Reader.
The intention is to improve (and minimize) diffs when dependencies
are changed and `make depend' is executed.
(1) use `makedepend ... -w 20'
(2) `sort -u' the resultant file with some more "magic".
(1) makes sure that there is only one dependent file per line,
(2) makes lines unique since `makedepend' can output one file
many times which is redundant and makes diffs hard to read.
This uses 'mv', 'grep', and 'sort' in all FLTK library Makefiles.
Image libraries are intentionally left for a later update.
Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32".
Replace "WIN32" in text and documentation with "Windows".
Replace "MSWindows" with "Windows".
To do: README.Windows.txt (and maybe other documentation as well)
needs updates.

Currently src/drivers/OpenGL/Fl_OpenGL_Graphics_Driver.cxx wouldn't
contribute any code to the lib, but it is kept for future extensions.
This file is no longer compiled (see src/CMakeLists.txt and src/Makefile).
Tested (only) under Windows and Linux.
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12381 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
As proposed in STR #2750 and #2752: only status quo, i.e.:
- no new method Fl_Input_Choice::maximum_size(int) (STR #2750 and #2752)
- no handling of FL_Down key to open menu (STR #2752)
