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
