       scrolltest - tests some scrolling algorithms with svgalib


       Smooth  scrolling  demo.  Uses three different techniques.
       Useful for testing Mode X functionality (not that I  would
       recommend  it  over  320x240x256 linear). Press <Space> to
       cycle through the demos.

       The demos works only in 320x240x256 for the first 2  tests
       and  with  320x200x256 in the last. Demos 1 & 3 use a vir-
       tual screen buffer, mode 2 (jumpy) works on  screen.  This
       is  more  a  skeleton  if you want to write some animation
       program, rather than a nice demo.

       Shows frames per second (multiplied by 10) for method 1  &
       3. Thus works also a kind of memory speed tester

       This  demo  is  part  of  svgalib  and can be found in the
       demos/ subdirectory of the original svgalib  distribution.
       However,  it  is  not  installed in the system by default,
       s.t. it is unclear where you can find it if  your  svgalib
       was  installed by some linux distribution. Even then, when
       you have the demo on your system, you probably won't  have
       the sources s.t. it is only of limited use for you.

       In case of any such problem, simply get an svgalib distri-
       bution from the net. You even don't need  to  install  it.
       Just  make  in  the demos/ subdirecty. As of this writing,
       svgalib-1.2.12.tar.gz is the latest  version  and  can  be
       retrieved     by     ftp     from    at
       /pub/Linux/libs/graphics     and     at
       /pub/linux/sources/libs  which  will most probably be mir-
       rored by a site close to you.

       This manual page was edited by Michael Weller <eowmob@exp->.  The  exact  source  of the referenced
       demo as well as of the original documentation is  unknown.

       It  is  very  likely that both are at least to some extent
       are due to Harm Hanemaayer <>.

       Occasionally this might be wrong. I  hereby  asked  to  be
       excused by the original author and will happily accept any
       additions or corrections to  this  first  version  of  the
       svgalib manual.
