The FAQ is slightly out of date on this issue. The Java 3D 1.1
implementation had a bug that prevented the readRaster operation from
working on the Solaris Java 1.2 production version. This bug has been
fixed in Java 3D 1.1.1. However, you still need to call readRaster
from postSwap.

>In the Java3D FAQ, a method is mentioned for capturing still (rendered)
