[enhancement] Add non-linear animation progress (e.g. a sigmoid function) for minimize/maximize

[enhancement] Add non-linear animation progress (e.g. a sigmoid function).

The current linear animations for minimize/maximize look kind of awkward and unnatural.

[kevin gunn (kgunn72)]

there's actually some animation in the latest image for this

[Daniel van Vugt (vanvugt)]

Running the latest Unity8 on wily desktop I can see the existing linear animations only. See bug description :)

[Daniel van Vugt (vanvugt)]

You will also see bug 1497083 during the maximize animation.

[Vesa Rautiainen (vesar)]

It would already be an improvement if instead of linear animation we would use the standard Ubuntu easing curve that is part of our SDK. UbuntuAnimation.StandardEasing.

I recommend first switching to use that and as part of the currently ongoing system animations alignment work we could consider if we need to add new easing curves to the sdk.

[Michael Zanetti (mzanetti)]

The linked branch uses UbuntuNumberAnimations as per Vesa's comment.

Animations will be refined when desing specs them out. For now I think this bug can be closed as the linked branch addresses the reporter's issue and it's an improvement over current trunk already.

[Daniel van Vugt (vanvugt)]

I'm not sure this bug was fixed or just slightly improved. The animation curve in Unity8 still feels ugly and unnatural compared to Unity7.
