Adaptive height with animation

[filtsin]

Add animation.rs with some math for animations and new features:

Params

Global:

• auto_height: true | false (default false): enable or disable adaptive height for content (Resolves #139)

List items section

• show_default: true | false (default true): enable or disable items list for empty input

New animation section (if it is present, then animations are enabled)

• height_duration_ms: for height animation

Thank you for review. I committed my changes and updated pr description.

Something wrong with the end of border calculation here I guess? (it's half of the size, so yes animation is enabled)

Also when I was taking a screenshot for some reason it plays animation from the original size.

Sorry, I can't understand what is the problem. Did you turn on the animation and nothing happened? What's your duration value?

[animation]
height_duration_ms = ?

There is one more param for height change: auto_height in global section. Did you set it? (Maybe remove this because we have height_duration_ms?)

Yeah, the screenshot was a really dumb way to explain the issue, sorry. I did enable animation and it mostly works. auto_height is also enabled. It should be independent of height_duration_ms value. See the demo:

Thank you. I reproduced it myself with hide_actions = false. I'll try to fix it

Can you check again with new changes?

Sorry no time for this pr and no interest. If someone want to continue work on animations welcome to take my code :). I'm using my branch for adaptive height but without animation (turns out it looks good)
