scrollable rasters within windows

[Paul Box]

Hello Swarm group

Is there a simple way to have a zoomraster display a scrollable subset of the 
raster that it is displaying?  For example, I have a raster that is 800 
columns by 2100 rows that I wish to show in a simulation, and with my best 
monitor I only have 1600 pixels vertical resolution.

It would be easy enough to write some filter to only display every other row 
and column (in effect set a zoom factor of .5), but I would rather be able to 
see all of the pixels at full resolution, and simply scroll up and down the 
picture as the thing is running.

Please excuse this if I'm asking a trivial question.  Hope summer's going 
well.
