+
+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.
