* SVGA/Mesa interface for Linux.
*/
/*
* 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.
