[Joelib-cvs] Minor bug fix in gui/molviewer/java3d/Viewer

[Gert S. <Ger...@re...>]

When no non-null GraphicsConfiguration3D-object could be created, because
of a wrongly configured graphics driver, an outdated graphics board or a
buggy java3d package, the ViewerFrame was still shown when calling the
Viewer main method.

For this reason a test has been added in the beginning of the Viewer main
method to check the ability to create a non-null
GraphicsConfiguration3D-object. An additional class,
joelib/test/TestJava3D, has been created to perform the testing.

Probably this test should be added at other places too.

Greetings,

Gert
