@Returns:
@alpha:
@Returns:
Maximum value of the alpha function. You should use this value to
scale the computed alpha value.
The alpha function is a function of time. You should provide a function
transforming the current position in the timeline.
@alpha: a #ClutterAlpha
@user_data: optional user defined data passed to the function
@Returns: a value between 0 and CLUTTER_ALPHA_MAX_ALPHA

@alpha:
@timeline:
@alpha:
@Returns:
Represents minimum and maximum thresholds for the smoothstep function. The
thresholds are values from <0,1> relative to the frame-length of the behaviour,
i.e., if the behaviour consists of 60 frames, threshold of 0.25 corresponds to
frame 15, and threshold of 1.0 to frame 60.
@min: lower threshold; a #ClutterFixed value from <0,1>
@max: upper threshold; a #ClutterFixed value from <0,1>
