The 1.2 Canvas constructor that takes a GraphicsConfiguration object as a
parameter is not working correctly.

In the Solaris environment a GraphicsConfiguration object will map to a
particular X11 visual. I have an example program that chooses a
GraphicsConfiguration object that has a single buffered RGB visual (VisualID 45)
associated with it. When the Canvas is created the visaul read back is
a double buffered RGB visual (VisualID 44).

The attached program demonstartes the problem. The program requires Java 3D
to run. I can provide a pointer to the Java 3D library.
