-This file contains jitter point arrays for 2,3,4,8,15,24 and 66 jitters.
-
-The arrays are named j2, j3, etc. Each element in the array has the form,
-for example, j8[0].x and j8[0].y
-
-Values are floating point in the range -.5 < x < .5, -.5 < y < .5, and
-have a gaussian distribution around the origin.
-
-Use these to do model jittering for scene anti-aliasing and view volume
-jittering for depth of field effects. Use in conjunction with the 
-accwindow() routine.
