Issue I426 [fly2,enhancement,resolved]
  In FLY2, new "window" standard_beam attribute.

  "window" works just like "pupil" except the particle
  velocity is in the opposite direction.

  As an example, define the source as a spherical distribution and the
  window as a point in the center of the sphere.  The particles will
  start on the sphere and move normal to the sphere surface (in on the
  convex side) rather than toward the sphere center (as in the pupil
  type).

  Added in 8.0.4-TEST10.
