       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/ subdirec-
       tory 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  <eowmob@exp-math.uni-es->.	 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.
