  11  * This library provides the basic functions for initializing and using\r
  12  * unchained (planar) 256-color VGA modes.  Currently supported are:\r
  13  *\r
  14  *        - 320x200\r
  15  *        - 320x240\r
  16  *\r
  17  * Functions are provided for:\r
  18  *\r
  19  *        - initializing one of the available modes\r
  20  *        - setting the start address of the VGA refresh data\r
  21  *        - setting active and visible display pages\r
  22  *        - writing and reading a single pixel to/from video memory\r
  23  *\r
  24  * The library is provided as a demonstration only, and is not claimed\r
  25  * to be particularly efficient or suited for any purpose.  It has only\r
  26  * been tested with Borland C++ 3.1 by the author.  Comments on success\r
  27  * or disaster with other compilers are welcome.\r
  28  *\r
  29  * This file is public domain.  Do with it whatever you'd like, but\r
  30  * please don't distribute it without the article.\r
