* Notes on FL_ABI_VERSION and deprecated (obsolete) FLTK_ABI_VERSION:
*
* (1) FLTK_ABI_VERSION is deprecated, but still defined below.
* Do NOT define FLTK_ABI_VERSION here - it would be overwritten later.
*
* (2) FL_ABI_VERSION is now (as of FLTK 1.3.4) defined by configure
* or CMake. Do NOT define it here. Its definition will be included
* below by "#include <FL/abi-version.h>".
*
* (3) If you use the provided IDE files (Windows VC++ or Xcode) you should
* edit the definition in the provided IDE subdirectory. The correct
* file is `/path/to/fltk/ide/<IDE-name>/FL/abi-version.h' .

FLTK defines some constants to help the programmer to
find out, for which FLTK version a program is compiled.
The following constants are defined:

The major release version of this FLTK library.

*/

/**
The minor release version for this library.
FLTK remains mostly source-code compatible between minor version changes.

minor and patch releases.
\deprecated This \p double version number is retained for compatibility
with existing program code. New code should use \em int FL_API_VERSION
instead. FL_VERSION is deprecated because comparisons of floating point
values may fail because of rounding errors. However, there are
currently no plans to remove this constant.
FL_VERSION is equivalent to <em>(double)FL_API_VERSION / 10000</em>.

The FLTK ABI (Application Binary Interface) version number as an \em int.
FL_ABI_VERSION is an \em int that describes the major, minor, and patch
ABI version numbers in the same format as FL_API_VERSION.
The ABI version number \p FL_ABI_VERSION is usually the same as the
API version \p FL_API_VERSION with the last two digits set to '00'.
FLTK retains the ABI (Application Binary Interface) during patch
releases of the same major and minor versions. Examples:
\verbatim
FLTK Version FL_API_VERSION FL_ABI_VERSION FL_VERSION (deprecated)
1.3.0 10300 10300 1.0300
1.3.4 10304 10300 1.0304

Version 1.2.3 is actually stored as 10203 to allow for more than 9
minor and patch releases.
The FL_MAJOR_VERSION, FL_MINOR_VERSION, and FL_PATCH_VERSION constants
give the integral values for the major, minor, and patch releases
respectively.
To enable new ABI-breaking features in patch releases you can configure
FLTK to use a higher FL_ABI_VERSION.
\todo Configuration of FL_ABI_VERSION needs documentation.

calling the Fl::event_*() methods. This static information remains
valid until the next event is read from the window system, so it
