var openingOvershootTension: Float
The tension (as a positive float) in an OvershootInterpolator applied on the FabOption when it's playing its animations for being shown from a hidden state (when the ExpandableFab is opening). The OvershootInterpolator allows us to have an animation where the FabOption will grow past its regular size when initially appearing, before smoothly shrinking down to regular size. Larger values will exaggerate the effort more. Default value is 3.5f.
