SpriteHandler_examples.h:

* Added define USE_DYNAMICS_SYSTEM which if true showcases integration of the sprite position (centroid) as a function of its velocity and acceleration. Affects Sprite0 in example1 now.
* Added define DBG_DRAW_SPRITES which is a simple way of toggling the debug drawing in both examples.
