It's more the "smoothing" between pixels that is disastering our stuff.  If you create 
a canvas of (basically) random color pixels, when you render a magnified version 
you get odd star bursts of colors and other odd things !?!  Sometimes we need
to just have pixel replication so we get squares of color.  Right now we have
to draw individual squares which tends to be deathly slow.  

Is there anyway to turn off the interpolating feature (?) so we can quickly render
what the computer is taking as random arrays of colors?
