Using the configuration routines.
This is a very simple program showing how to use the allegro
config (ini file) routines. A first look at the example
shows nothing more than a static graphic and the wait for
a keypress. However, the way this graphic is displayed is
configured through a custom exconfig.ini file which is loaded
manually. From this file the example obtains parameters like
fullscreen/windowed mode, a specific graphic resolution to set
up, which graphic to show, how to blit it on the screen, etc.
