Code Clean-Up based on our Recommended Settings (jogamp-scripting c47bc86ae2ee268a1f38c5580d11f93d7f8d6e74)

- Change non static accesses to static members using declaring type
        - Change indirect accesses to static members to direct accesses (accesses through subtypes)
        - Add final modifier to private fields
        - Add final modifier to method parameters
        - Add final modifier to local variables
        - Remove unnecessary casts
        - Remove unnecessary '$NON-NLS$' tags
        - Remove trailing white spaces on all lines
