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.

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.
