SMOOTHABLE ANIMATIONS (BOZZA) ------------------------------------------------------------------------------ A smoothable [animation] can produce fluid graphic effect (such as movement, appearing/disapearing, etc.) with discrete changes of the expression that define the [animation] state. With a fluid animation, for example, a boolean state can produce a fluid animation between two states. A smoothable [animation] is [delayable] also. 1. Smooth parameters These parameters define how the transition from a state to another is performed: * Smooth speed: expressed in some UM/s (for example %/s for an [Opacity animation], pixel/s for an [Horizontal move animation], °/s for a [Rotation animation]) define how quickly the transitions will occur. Zero means no smooth (transitions will be performed instantly. * Curve: the speed factor when the transition start, and the divisor when the transition ends. * a value of 1 means that the transition will be uniform (constant speed); * a value greater than 1 means that the transition starts faster and ends slower; * a value less than 1 means that the transition starts slower and ends faster. * Max delta: for some animation define the maximum transition distance that will be performed in a fluid way. Transitions grater than this value will be performed instantly.
