[vtkusers] Delete() usage

[Sebastien Jourdain]

Are you in C++ or in Java. Looking at the code, it looks like Java.

If you are in Java, you are almost fine, you just need to call or
setup the specific VTK Garbage collector. No need to call Delete()
manually.

For more details, you can look at the Java sample code, which
illustrate how to initialize it to make it run in the background,
otherwise you can manually call it from your code.

By default, it is not started and therefore, the memory is never released.
