Velocity(speedState) animation helper state-like

[Dionysusnu]

This is currently not great to do, usually having to update another state on heartbeat, incrementing it with the current speed.
This helper would wrap that behaviour.
It could also have wrap-around behaviour where it loops around a number range like an integer overflowing. This would for example be useful for an infinitely rotating loading circle.
Adding is probably subject to #40

Could you be more specific about what this does? Is it similar to #12?

[Dionysusnu]

Overlooked that.. yeah that's a duplicate. As long as timers receive wrapping and variable speed behaviour, they cover all the behaviour I requested here.

@Elttob it may be more clear to add a status: duplicate instead of rejected, since the suggestion will still be implemented (assuming the other issue is approved)
