Standard Effects

[Klaim]

Specify a set of effects that should be available on in all players.

First choose the list of effects, then add them to the specification with how to set their data.
For a first version, a combination of common tweening effects from JQuery, Cocos2D and other widely used libraries should work fine and be easy to implement in players.

All effects are function of either time or an input value. If an effect is set to rely on time, it would just be executed through time and end. If an effect is set to rely on input, then the effect behaviour will depend on the value of the input, which varies between 0 and 1. The input value changes are implementation-dependant.
