  2.                                       ^
  3. In the following frames, I will show  ^
  4. features of most of the routines in   ^
  5. the Library.                          ^
  6.                                       ^
  7. These routines are specifically for   ^
  8. VGA hardware, allowing developers to  ^
  9. incoroporate these features without   ^
  10. overhead of supporting older boards.  ^
  11.                                       ^
  12. This Library also offers much more    ^
  13. capabilities than that which comes    ^
  14. with high level language compilers.   ^
