[vtkusers] Is it possible to replace DrawingSurface in vtkPanel.java?

[Hong, Lichan <hong@parc.xerox.com>]

DrawingSurface, a deprecated API of Java, is currently used in the sample code of vtkPanel.java.
It appears that this API has been dropped from JDK1.4 (I tried to compile my Java code with
JDK1.4.0-RC this morning and the compiler cannot find class DrawingSurface). 

Has anyone figured out how to replace DrawingSurface in vtkPanel.java? If so, how?

Thanks.
