Fix: Memory consumption

Observing memory consumption showed:
    1 - 'traceLock' debug stack traces (GLContextLock)
    2 - massive Iterator usage

(1) is fixed, ie only enabled in DEBUG mode, like we have done in RecursiveLock before

(2) Using an Iterator on ArrayLists with a low element count < 100,
    as it is usual in our use cases, is observed not to be faster
    than accessing the elements via an index (-> TestIteratorIndexCORE.java ).
    On the contrary, the index implementation was a bit faster.
    Further more, these Iterators were massively used on the fly during animation,
    hence their memory managment even impacts fluent processing/animation.
    Recoded all animation related (display, surfaceUpdated, ..) loops using an index.
