+            desktopCameraRig is parent of desktopCamera. 
+
+            desktopCamera rotates, so it pivots in place.
+            desktopCameraRig is moved to head bone, local position of camera is viewpoint offset when standing
+
+            if rig was moving position & rotation, this would work
+            but because rig handles position and camera handles rotation, camera pivots in place instead of at correct point
+            which is gross
