Title: A more classic animation approach to transitions

changed animation of entry and exit to avoid using opacity. Entering data is animated to zoom in from its origin and exiting data takes the shortest path towards the edge of the canvas while shrinking down. This helps with continuity of what is entering and exiting a scene, more analogous to our non digital world :)
