47//
48// Examiner viewer - allows the user to change the camera position
49// by spinning a sphere in front of the viewpoint.
50//
51//
52// Keys used by this viewer:
53// -------------------------
54//
55// Left Mouse: Tumbles the virtual trackball.
56//
57// Middle Mouse:
58// Ctrl + Left Mouse: Translate up, down, left and right.
59//
60// Ctrl + Middle Mouse:
61// Left + Middle Mouse: Dolly in and out (gets closer to and further
62// away from the object).
63//
64// Shift + Ctrl + Left Mouse: Dolly in and out (same as Left + Middle
65// behavior but added by VSG to support the
66// standard Microsoft 2-button mouse).
67//
68// <s> + click: Alternative to the Seek button. Press (but do not hold
69// down) the <s> key, then click on a target object.
70//
71// Right Mouse: Open the popup menu.
