       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 virtual 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 distribution 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 mirrored by a site close to you.

       This manual page was edited by Michael Weller <[email protected]>. 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 <[email protected]>.

       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.
