       This  program  demonstrates  how  to  load  and display bitmap files in truecolor video modes, and how to
       crossfade between them.  You have to use this example from the command line to specify  as  parameters  a
       number  of  graphic files. Use at least two files to see the graphical effect. The example will crossfade
