/**
* @file main.c
* Program entry point, global variables and global functions.
*
* @mainpage
* GrafX2 is a bitmap paint program inspired by the Amiga programs
* Deluxe Paint and Brilliance. Specialized in 256-color drawing,
* it includes a very large number of tools and effects that make
* it particularly suitable for pixel art, game graphics,
* and generally any detailed graphics painted with a mouse.
*
* The program is mostly developed on Haiku, Linux, FreeBSD
* and Windows, but is also portable on many other platforms :
* It can be built using SDL 1.x or SDL 2.x libraries (see https://www.libsdl.org/)
* or Xlib or Win32 API.
*
* Web for the project users is http://grafx2.tk/.
*
* Developpers are welcome to contribute :
* the code is hosted on gitlab https://gitlab.com/GrafX2/grafX2
* and a bug tracker, wiki, etc. is available on
* https://pulkomandy.tk/projects/GrafX2.
*
* This Doxygen documentation is browsable on
* https://pulkomandy.tk/projects/GrafX2/doxygen/ (updated nightly).
*
* The inline help is also available here :
* http://pulkomandy.tk/GrafX2/
