Vent/Scrubber Animation Transitions

[cosmiccoincidence]

Summary

Currently, vents and scrubbers have 3 different states (not referring to their function, just the animations):

• Stopped
• Spinning
• Spinning Fast

When changing the vent/scrubber's function it changes the animation state to match, but currently there are no transitional animations between these 3 main states. We need:

• [ ] Transitional animations between the 'stopped' and 'spinning' states (fan starts to spin and gradually picks up speed to match the 'spinning' state) for both the vent AND scrubber. (Can be reversed.)
• [ ] Transitional animations between the 'spinning' and 'spinning fast' states (fan is spinning and gradually picks up speed to match the 'spinning fast' state) for both the vent AND scrubber. (Can be reversed.)

Current Behavior

Currently they just jump from one state to the other which doesn't look good.
