/**

 * Names of Effects one can add to the DistortedEffects queues.

 * <p>

 * Effect's 'Type' is one of the constants defined in {@link EffectType}.

 * </p>

 * <p>

 * Effect's 'Uniforms' are a vector of 7 (matrix effects) 12 (vertex) or 8 (fragment) floats, which

 * together form full information how to compute a given effect.

 * Typically, some of those values will be Interpolated in CPU (by one of the 'EffectQueueX.compute()'

 * methods) and the effect of such Interpolation sent to the Shaders.

 * </p>

 * <p>

 * Effect's 'Unity' is such a particular vector of its 'interpolated values' which makes the

 * effect NULL. For example, if the effect is 'MOVE' by a 3-dimensional vector, then a 'NULL

 * MOVE' is a MOVE by vector (0,0,0), thus (0,0,0) is the unity of the MOVE effect.

 * This is used by the EffectQueue classes to decide if the final form of the Effect is NULL - and

 * thus if it can safely be removed from Effect Queues without affecting the visual in any way.
