  Subject - Pratt's Algorithm

My professor mentioned that there is an algorithm relating to windowing
systems and in particular  (?) scrolling windows which he claims is
entitled "Pratt's Algorithm".
Does anyone know a reference to it or can they give me a description of
it?

Subject: Unusual RGB Video Distribution Problem
From: MHARRIS@A.BBN.COM

Dear wizards --

I am generating three images, each 320x200 pixels (HxV), on a 1024x768
bitmap graphics system (output is RGBS, 60Hz, non-interlaced).  I want to
put up each of the three images on a separate monitor (RGBS, 640x480, 30Hz
non-interlaced) such that it fills its monitor screen, without spending
Big Bux.  I think I know how to do it for $10k+ per monitor: use lots of RGB
switchers.  The source images can be placed anywhere convenient on the source
screen, and stay there.  No fair encoding the source image into NTSC: too much
resolution is lost.  Do you know where to buy, or how to build, a relatively
simple black box to do this thing?  I need to do it to at least 16 monitors
and maybe 256 (!), so perhaps economies of scale are relevant?

Please respond SOON if you have any ideas.  Many thanks.
