Zoomed in, the player's view is drawn once more, from the weapon along
its aim through the zoom's field of view, into a small square of the
back buffer (the first-person weapon left out), and shown on a disc over
the barrel that magnifies what it covers of the view by the zoom's
magnification (vr.scope_size). The weapon's zoom mask and filters no
longer darken the HUD before the eyes.
