DESCRIPTION

       This  program  demonstrates  how  to  use  the  get_camera_matrix()  function to view a 3d world from any
       position and angle. The example draws a checkered floor through a viewport region on the screen. You  can
       use  the keyboard to move around the camera or modify the size of the viewport. The keys that can be used
       with this example are displayed between brackets at the top of the screen.
