-This allows manipulation of many of the visual gear values of the visual gear `vgUid`. All visual gear values are numbers. Each visual gear may be using these parameters differently, but the *usual* meaning of these is the following:
+This allows manipulation of the internal state of the visual gear `vgUid`. If `vgUid` is invalid or the `vgUid` does not refer to an existing visual gear, the function does nothing- Thus, you can safely call this function even if you are not sure if the visual gear actually exists.

 Note that most visual gears require little to no modification of their values.
