removeSprite() removes a face of the container, not the sprite

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create 3D object (tested with Sphere)
2. add sprite to object using addSprite() (tested with MovieClipSprite)
3. try to remove sprite using removeSprite()

What is the expected output? What do you see instead?
The sprite sent as the argument for the removeSprite() method should be removed 
from its parent.  Instead, the parent removes a face and leaves the sprite in 
place.

What version of the product are you using? On what operating system?
Away3D 3.6.0, Windows 7 x64
