<BLOCKQUOTE>An ImposterSprite is a textured quad which is rendered in place a
3D geometry. The ImposterSprite is generated by rendering the original
3D geometry to a texture as an image cache. The ImpostorSprite is
automatically generated by the osgUtil::CullVisitor so it not
necessary to deal with it directly.</BLOCKQUOTE>

<DD>Get the control coordinates of the corners of the quad.
The control coordinates are the corners of the quad projected
out onto the front face of bounding box which enclosed the impostor
geometry when it was pre-rendered into the impostor sprite's texture.
At the point of creation/or update of the impostor sprite the control
coords will lie on top of the corners of the quad in screen space - with a pixel error
or zero. Once the camera moves relative to the impostor sprite the
control coords will no longer lie on top of the corners of the quad in
screen space - a pixel error will have accumulated. This pixel error
can then be used to determine whether the impostor needs to be updated.
Stored in the order, [0] - top_left, [1] - bottom_left, [2] - bottom_right, [3] - top_left.
