I have to see if it would work with my design goal. The basic goal is to
have two totally different environments work together as if they we one
environment. One screen would be X windows and the other screen would be
a linux framebuffer implementation. The problem is two very different
environments are going to have two different toolkits. Since it is
possible to pass in a GraphicsConfiguration to a Frame, Window etc I was
thinking it would be easiest to grab the proper toolkit from the
GraphicsConfiguration. Do you see any other way to grab the proper
