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