    00028  * Intro to using the VGA/Mesa interface
    00029  *
    00030  * 1. #include the <vga.h> file
    00031  * 2. Call vga_init() to initialize the SVGA library.
    00032  * 3. Call vga_setmode() to specify the screen size and color depth.
    00033  * 4. Call SVGAMesaCreateContext() to setup a Mesa context.  If using 8-bit
    00034  *    color Mesa assumes color index mode, if using 16-bit or deeper color
    00035  *    Mesa assumes RGB mode.
    00036  * 5. Call SVGAMesaMakeCurrent() to activate the Mesa context.
    00037  * 6. You can now use the Mesa API functions.
    00038  * 7. Before exiting, call SVGAMesaDestroyContext() then vga_setmode(TEXT)
    00039  *    to restore the original text screen.
    00040  *
    00041  * Notes
    00042  * 1. You must run your executable as root (or use the set UID-bit) because
    00043  *    the SVGA library requires it.
    00044  * 2. The SVGA driver is not fully implemented yet.  See svgamesa.c for what
    00045  *    has to be done yet.
